Take a look at this.

Please, has anyone heard about www.drarg.com and their recent recruitment advert? Is the organization real?

Conoil atf dexron 11d on an electronically controlled gear box!!!?
Just follow your mechanic advice.

I do not know the difference though, but it's a Conoil Quatro ATF

sooperrescue:
Sorry about that. First I want to know the particular atf that you used on the gear. Secondly just change the gear brain box and everything will be fine

I used a Conoil ATF.

I ran a scan afterwards and the scan read:

P0721, P0731 after each scan and the problem persists after clearing the codes.

My mechanic advised a change of gearbox.

Not too late for me...I made a very silly mistake, am ashamed of myself.

Hello @Siena

I have a similar issue recently with my Volkswagen Jetta 2009.

I was on a trip and it suddenly began to rev without switching gears. I ended up changing transmission fluid and running a scan. The scan results reads:

P0721, P0731, P0751 at different scans, along side output shaft speed sensor circuit range/performance. After clearing the codes, the problem persists.

Now the mechanic advised a change of gear box.

Please, help me out, as buying a gear box is way out of my budget for now.

I use a Volkswagen Jetta 2009 with an automatic transmission. It suddenly had difficulty switching gears. So I changed the transmission fluid, but the problem persists.

I have also done a scan on the car, and the code shows P07031. After clearing the code, the seems to be okay from the dashboard, but it still has difficulty initialising speed and switching between gears.

Who can help, please?

A friend's got a 3rd class BSc.Ed and intends to go for MIT OR MBA. Please advice.
Thanks.

The set is the Riemann sphere, which is of major importance in complex analysis . Here too is an unsigned infinity – or, as it is often called in this context, the point at infinity . This set is analogous to the real projective line, except that it is based on the field of complex numbers . In the Riemann sphere, , but is undefined, as is . The negative real numbers can be discarded, and infinity introduced, leading to the set [0, ∞], where division by zero can be naturally defined as a/0 = ∞ for positive a. While this makes division defined in more cases than usual, subtraction is instead left undefined in many cases, because there are no negative numbers. In higher mathematics Although division by zero cannot be sensibly defined with real numbers and integers, it is possible to consistently define it, or similar operations, in other mathematical structures. In the hyperreal numbers and the surreal numbers , division by zero is still impossible, but division by non-zero infinitesimals is possible. In distribution theory one can extend the function to a distribution on the whole space of real numbers (in effect by using Cauchy principal values ). It does not, however, make sense to ask for a 'value' of this distribution at x = 0; a sophisticated answer refers to the singular support of the distribution. In matrix algebra (or linear algebra in general), one can define a pseudo-division, by setting a / b = ab+ , in which b + represents the pseudoinverse of b. It can be proven that if b −1 exists, then b+ = b −1 . If b equals 0, then b+ = 0; see Generalized inverse . Any number system that forms a commutative ring—for instance, the integers, the real numbers, and the complex numbers—can be extended to a wheel in which division by zero is always possible; however, in such a case, "division" has a slightly different meaning. The concepts applied to standard arithmetic are similar to those in more general algebraic structures, such as rings and fields . In a field, every nonzero element is invertible under multiplication; as above, division poses problems only when attempting to divide by zero. This is likewise true in a skew field (which for this reason is called a division ring). However, in other rings, division by nonzero elements may also pose problems. For example, the ring Z/6 Z of integers mod 6. The meaning of the expression should be the solution x of the equation . But in the ring Z /6 Z, 2 is a zero divisor. This equation has two distinct solutions, x = 1 and x = 4, so the expression is undefined. In field theory, the expression is only shorthand for the formal expression ab −1 , where b −1 is the multiplicative inverse of b. Since the field axioms only guarantee the existence of such inverses for nonzero elements, this expression has no meaning when b is zero. Modern texts include the axiom 0 ≠ 1 for fields so that the zero ring is excluded from being a field. In computer arithmetic Most calculators, such as this Texas Instruments TI-86 , will halt execution and display an error message when the user or a running program attempts to divide by zero. Division by zero on Android 2.2.1 calculator shows the symbol of infinity. The IEEE floating-point standard , supported by almost all modern floating-point units , specifies that every floating point arithmetic operation, including division by zero, has a well-defined result. The standard supports signed zero, as well as infinity and NaN (not a number). There are two zeroes: +0 (positive zero ) and −0 ( negative zero ) and this removes any ambiguity when dividing. In IEEE 754 arithmetic, a ÷ +0 is positive infinity when a is positive, negative infinity when a is negative, and NaN when a = ±0. The infinity signs change when dividing by −0 instead. The justification for this definition is to preserve the sign of the result in case of arithmetic underflow. [3] For example, in the single- precision computation 1/( x/2), where x = ±2 −149 , the computation x/2 underflows and produces ±0 with sign matching x , and the result will be ±∞ with sign matching x . The sign will match that of the exact result ±2 150 , but the magnitude of the exact result is too large to represent, so infinity is used to indicate overflow. Integer division by zero is usually handled differently from floating point since there is no integer representation for the result. Some processors generate an exception when an attempt is made to divide an integer by zero, although others will simply continue and generate an incorrect result for the division. The result depends on how division is implemented, and can either be zero, or sometimes the largest possible integer. Because of the improper algebraic results of assigning any value to division by zero, many computer programming languages (including those used by calculators ) explicitly forbid the execution of the operation and may prematurely halt a program that attempts it, sometimes reporting a "Divide by zero" error. In these cases, if some special behavior is desired for division by zero, the condition must be explicitly tested (for example, using an if statement). Some programs (especially those that use fixed- point arithmetic where no dedicated floating- point hardware is available) will use behavior similar to the IEEE standard, using large positive and negative numbers to approximate infinities. In some programming languages, an attempt to divide by zero results in undefined behavior. The graphical programming language Scratch 2 used in many schools returns Infinity or -Infinity depending on the sign of the dividend. In two's complement arithmetic, attempts to divide the smallest signed integer by are attended by similar problems, and are handled with the same range of solutions, from explicit error conditions to undefined behavior. Most calculators will either return an error or state that 1/0 is undefined, however some TI and HP graphing calculators will evaluate (1/0) 2 to ∞. Microsoft Math and Mathematica return ComplexInfinity for 1/0. Maple and Sage return an error message for 1/0, and infinity for 1/0.0 (0.0 tells these systems to use floating point arithmetic instead of algebraic arithmetic).

In algebra It is generally regarded among mathematicians that a natural way to interpret division by zero is to first define division in terms of other arithmetic operations. Under the standard rules for arithmetic on integers , rational numbers, real numbers , and complex numbers, division by zero is undefined. Division by zero must be left undefined in any mathematical system that obeys the axioms of a field. The reason is that division is defined to be the inverse operation of multiplication . This means that the value of a /b is the solution x of the equation bx = a whenever such a value exists and is unique. Otherwise the value is left undefined. For b = 0, the equation bx = a can be rewritten as 0x = a or simply 0 = a. Thus, in this case, the equation bx = a has no solution if a is not equal to 0, and has any x as a solution if a equals 0. In either case, there is no unique value, so is undefined. Conversely, in a field, the expression is always defined if b is not equal to zero. The concept that explains division in algebra is that it is the inverse of multiplication. For example, since 2 is the value for which the unknown quantity in is true. But the expression requires a value to be found for the unknown quantity in But any number multiplied by 0 is 0 and so there is no number that solves the equation. The expression requires a value to be found for the unknown quantity in Again, any number multiplied by 0 is 0 and so this time every number solves the equation instead of there being a single number that can be taken as the value of 0/0. In general, a single value can't be assigned to a fraction where the denominator is 0 so the value remains undefined (see below for other applications). 0/0 is known as indeterminate . For more details on this topic, see Mathematical fallacy . It is possible to disguise a special case of division by zero in an algebraic argument,[2] leading to spurious proofs that 1 = 2 such as the following: With the following assumptions: The following must be true: Dividing by zero gives: Simplified, yields: The fallacy is the implicit assumption that dividing by 0 is a legitimate operation with the same properties as dividing by any other number. In calculus At first glance it seems possible to define a /0 by considering the limit of a / b as b approaches 0. For any positive a , the limit from the right is however, the limit from the left is and so the is undefined (the limit is also undefined for negative a ). Furthermore, there is no obvious definition of 0/0 that can be derived from considering the limit of a ratio. The limit does not exist. Limits of the form in which both ƒ (x ) and g (x ) approach 0 as x approaches 0, may equal any real or infinite value, or may not exist at all, depending on the particular functions ƒ and g (see l'Hôpital's rule for discussion and examples of limits of ratios). These and other similar facts show that the expression 0/0 cannot be well-defined as a limit.

No, this is not valid. First, division by zero is undefined. We can stop right there if we like. But further, in the fourth line of the "answer," (10-10)/(10-10) is taken to equal 1 (as it is cancelled out). But as 10-10=0, this means that 0/0=2 is a contradiction of this assumption. This is another hole in the argument.

I admire the reasoning of that young fellow. However, difference of two squares doesn't hold here because
(a^2-b^2)=(a+b)(a-b)
but
(a^2-a^2)
CANNOT AND WILL NEVER BE EQUAL TO
(a+a)(a-a)
because the CONVERSE, ie the reverse is not true; it will give 0 and not (a^2-a^2)
Hence, his/her hypothesis is ABSOLUTELY wrong.
