ohh so sorry guys , got really busy with school tinz ...but nonetheless the quiz/ game will hold by his grace .

BTW: any 1 is free to host it b4 I get ready. ,plz feel free to post & solve calculus questions here



greetings ..



1luv

#shalom..

montty:
Hmmm I have missed

Not at all my boss , the prof. himself.

personal59:
Pls help m with this question

Double differentiation of Y with respect to X

Y= 2A sin2P Vt. Cos2P X/N


Thanks waiting for d ans in anticipation god bless

hey, my guy make your question clear , or better still , snap & post .

phr33man:
ok

differentiate my answer & see .

phr33man:
wrong here's the answer:in(xInx)/Inx+1

jazz...wait o..I didn't even pick pen ..


I just rushed @ d question...


leme ....see...

.

ValentineMary:
Help me differenciate log3 base x. Thanks

forward your questions to the math clinic not here .

OK guys , the game starts. tomorrow by 7pm.










BTW: exercise your brains with this

$(3x+2)/(x^4 +4) dx

Daughterzion:
Let the questions roll in na

Lolz , can't wait right ?.

don't worry Asap.

phr33man:
integrate: dx/xInx

ln(lnx) + k





integrate cotxsec^ 2 x

bolkay47:
xlnx-x+K

correct

your question ..

.?

phr33man:
d ans is y=e^3x + c

y=x^x
find

dy/dx=?

correct !!

dy/dx = x^x( lnx +1)



integrate lnx dx

Ok guys , the issues now is Timing ,

when do you think will be the best time ?. morning , evening or night .?




all vote now ..

hmmm.

DesChyko:
Ans: 3x^2 + 2x + 1 + c

Ques: y = 4x/x^2
dy/dx =

+C?. hmm...wrong

well , yours

y ' = -4/x^2

ques


integral of 3e^(3x). dx. =?

hey guys , how good are you with calculus , ?.

well let's see , its just about solving simple problem then drop one.

let's have fun,....



here we go



try this


if y= x^3 +x^2 +x+1

dy/dx = ?.

cheep abi .? Lol..

fall in..

Hey, guys greetings to the entire Nairaland family , I'm Benjamin .K a.k.a benbuks , a mathematician (calculus lover ) by passion & a statistician by profession .

Just thought of creating this interesting & educative thread for all those interested , its purely calculus (differential or integral with maybe ODE)

Questions will be posted , first to post correct answer (maybe + solution) gets 5pts , then person with the highest number of point at the end the day wins N200 airtime of any network , then that person will host the next contest . in similar manna on & on ,


questions/ contributions /criticisms. welcomed .

jackpot:
I'm suspecting these were your assignments in Coordinate Geometry/ Elementary Mathematics II. Guess you think we're robots, and I know you'll be acting up superstar for ur class.

Okay na, kontinuuuuuuuu

;Dlol

guess that's why rechiez calls it mathematics clinic , me don tire to solve , untill i see sweet sweet questions/problems


#watchingtinz...

Laplacian:
x⁴=4^x
first; (x⁴)^1/x=4, since the RHS is an integer, x must divide 4;
similarly;
x=(4^x)^1/4, again since LHS is an integer, 4 must divide x.
Hence, if x divides 4 and 4 divide x, then x=4.

For; 3x=8^x, since 3 cannot divide 8, no integer x can satisfy that equation

yea man , got that , but you see the 2nd 1 becomes a challenge , that's why I said there exist no general rule to solving such .

jackpot:
another angle of attack, that's cool

d guy like modular arithmetic too much .hhmm


@ prof. Laplacian I hail oo.

Cymbal:
kindly show the workings!

x=(pX2+qX1)/(p+q)

y=(pY2+qY1)/(p+q)
Where x,y={(4b-2a),(9c-a)}
X1,Y1={(a+b),(3c+5a)}

X2,Y2={(5b-3a),(11c-3a)}
4b-2a={(5b-3a)p+(a+b)q}/(p+q)

P(a-b)=3q(a-b)
P=3q
hence
p:q=3:1

Cymbal:
Find in what ratio the points; (4b-2a , 9c-a) divides the line joining the points (a+b , 3c+5a) and (5b-3a , 11c-3a).

3:1

jackpot:
google functional equations

try this dear let's see.

How will I go about this plz..?.
The function f(x,y) satisfies
1) f(0,y)=y+1
2)f(x+1,0)=f(x,1)
3)f(x+1,y+1)=f(x,f(x+1,y)) for all non negative integers x,y.
determine f(4,1981)

jackpot:
i use to tell the junior ones that it is easier to destroy a house than to build. Same way it's easier to differentiate than to integrate.

yea , exactly the point.

Videx1:
agentofchange is that all about moment generating function

sir, you want me to post a text book on it here right ?

hmm., c'mmon bruv , surf the net na .? or bring up questions on it . guess that would help .

factorial1:
May not be able to type the solutions tonight but lemme give an Hint to solving question 2.
Since 4^x = 8x... Divide both sides by 4 to get 4^(x-1) = 2x.
Don't forget 4^(x-1) can be written as (1 + 3)^(x-1)... equating that to 2x gives
(1 + 3)^(x-1) = 2x... Then solve using Binomial Expansion . The answer should be 2 and 0 cause it will surely lead to quadratic equation. Note that you only need the first 3 terms of the expansion.

nice try sir, av known of this method too but the problem is , its still an approximate, since we truncate @ the 3rd term of expansion , why not 4th or 5th or higher ?. that's because we already know the answer to be 2 by trial -by-error , which is not always the ideal way of solving mathematical problems .


Now can it work for this ?

4^x = x^4 .?

or 3x = 8^x

factorial1:
Lol... By finding the integral of course, which I'm sure won't be quite easy.

sure , that's the point .

Nature130:
Help me with these questions ; find the values of x and y in ; x^y+y^x=17 and x+y=5. (2) find the value of x in 4^x=8x.

there exist NO analytical solutions to such equations yet , except approximate or graphical

though

1) (x,y) =(2,3)=(3,2)

2) x=2

you could be the first mathematician to develop that ,

happy trying .

@ factorial1 u try sir ,

differential calculus is quite cheep , but even though integral calculus is the reverse of it , its not usually funny to do so . Now in this regards , how can we then obtain back the integrand .?

Nwiboazubuike:
Differentiate X^x^x

x^x^x[ x^x(lnx+1)lnx + x^(x-1) ]



don't ask 4 workings except u wanna learn not test our intelligence.
