mathefaro: (1) the woman had 10% of the cost. 10% of the cost is 10/100 × N400 = N40 the man had 40% of the remainder. the remainder is N400- N40= N360 40% of the remainder is 40/100 × N360= N 144 the both had N184 altogether (2) Total marble in the bag= 5+4+x= 9+x probability of picking a red marble; x/(9+x) =2/5 cross multiply to get; 5x= 18+2x solve the linear equation to get; x= 6 (3) radius of the circle: 7cm length of the arc: 6cm first obtain the angel of the arc in degree, then proceed to use; area of a sector= pir²¢/360 2pir¢/360 =6 pi= 22/7 (2×22/7 ×7¢)/360=6 44¢/360=6 A¢=6 ( A=44/360) ¢= 6/A ¢= 49° area of the sector is; 49×22/7×49/360= 20.96cm2 (4) Gradient of the slope of the curve of y= 2x2 + 5x -3 at (1,4) NB: the (1,4) is the coordinate (x,y) first differentiate the equation of the curve to obtain; y' = 4x + 5 ______(1) obtain the gradient of the slope of the curve by substituting for x in equation (1) y' = 4(1) + 5 = 9 NB: y' is not y, it is the first derivative of y. Equation of the slope; (x-1)/(y-4) = 9 (this is synonymous to slope=(x2-x1)/(y2-y1) ) cross multiply to get; x-1 = 9y - 36 9y - x = 35 you didn't show up in chemistry thread, please we need more tutors in the thread. |

(1) Find the normal to the slope of the curve y= x2 - 9 at x= 3. (2) Find the geometric mean of the series 2, x, 25/2, hence find x. (3) 6cosx + 9sinx = 10, find x (4) find the integral of tanx |

icecalm:I'm sorry, this is not correct. Actually this formula you used is for getting area of the triangle inscribed in the sector. The area of a sector has a formula different from this... Check it out please. Put a mention on my handle in the chemistry thread so that I can lend a helping hand when it's needed. Good morning to y'all |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by Nobody: 7:51pm On Oct 29, 2015 |
mathefaro:the problem here is that, I couldn't remember what a sector really is, oh, is the sector that bounded portion by the radii of the circle? |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by mathefaro(m): 5:58am On Oct 30, 2015 |
icecalm:exactly |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by Nobody: 11:39am On Oct 30, 2015 |

Please you guys should create a thread for physics...and also, is there any maths freak that lives in uyo here? Please holla...i really need you, thanks |

What happened to this thread? Let's help out while we can shall we. I volunteer to take section IV - Calculus tutorial. SECTION IV: CALCULUS I. Differentiation: (a) limit of a function; (b) differentiation of explicit algebraic and simple trigonometric functions - sine, cosine and tangent. 2. Application of differentiation: (a) rate of change (b) maxima and minima 3. Integration: (a) integration of explicit algebraic and simple trigonometric functions. (a) area under the curve. I call on our able moderators and all maths gurus on this forum to lend a helping hand in demystifying mathematics for the younger generation.

SECTION II - POLYNOMIALS (A) CHANGE OF SUBJECT OF FORMULA A formula is an equation containing two of more variables and it describes how the variables are related. Example 1: The formula I = PTR/100 is used for finding simple interest where P = Principal, R = Rate and T = Time. Observe that the same letter can stand for different quantities in different formula. To find the Principal (P) from I = PTR/100 I = PTR/100 Multiply both sides by 100 100I = PTR Divide both sides by TR P = 100I/TR We can also find Time (T) by applying the same principles. I = PTR/100 Multiply both sides by 100 100I = PTR Divide both sides by PR T = 100I/PR CLASS WORK: (1) Make R the subject of formula if I = PTR/100 Change of formula to be continued shortly.… 1 Like |

thankyouJesus: Sir, which application do you use that makes your math look so orderly? I don't like the idea of write power as(^) and square root as sqrt. I want people to see the real thing. |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by Geofavor(m): 5:52pm On Dec 09, 2015 |
Mathemagician1:you can also do so without an app, sir. Let's say you wanna type 2^2, Just type like this, 2[sup]2[sup].... for 2base2, type 2[sub]2[sub] ... But remember to put a backslash in the second parenthesis in each case. |
Re: Nairaland 2016 Jamb Tutorial Classroon [mathematics Thread] by thankyouJesus(m): 6:00pm On Dec 09, 2015 |
Mathemagician1:Sir ke, me na small boy o. For power, use [sup]the power stuff[/su p]without the space. Eg 2x^(y-4) =2x[sup](y-4)[/su p] remember, without the space. |
