I don't understand it well !!!!
Please explain this question
F(x)=sin(x)       x belongs (-pi,pi)

#327 Re: Help Me ! » Differntiation » 2017-03-15 04:00:38

Now we must differentiate the a^2.  But 'a' is a constant.  It's gradient function is zero whatever x is.
What is gradient function!!!!

#328 Re: Help Me ! » Differntiation » 2017-03-15 03:59:21

Dy /dx is not equal to zero but da\dx is zro plz explain? ??

#329 Re: Help Me ! » Differntiation » 2017-03-15 03:58:11

Why we differentate wrt x???

#330 Re: Help Me ! » Differntiation » 2017-03-15 03:53:46

If you have not met this rule before, please ask about it.
Hehe I am well aware

#331 Re: Help Me ! » Differntiation » 2017-03-14 15:35:26

Minus y divide by x is ans

#332 Re: Help Me ! » Differntiation » 2017-03-13 13:56:04

When we take dy/dx it's not equal to zero when we take da/dx it's equal to zero how ????

#334 Re: Help Me ! » Differntiation » 2017-03-12 03:43:10

I solve dy by dx how further solve for y2

Help for this question
Find y2
X^2+y^2=a^2

#336 Re: Help Me ! » Extreme values » 2017-03-10 15:03:27

The only roots are 0 and 0. So (0,1) is a possible local extreme.
Why you not wote (0,1)
How y axis is 1

#337 Re: Help Me ! » Extreme values » 2017-03-10 15:01:24

Why
We set that to 0 and solve:

#338 Re: Help Me ! » Increasing and decreasing concept » 2017-03-09 01:27:45

i perform all calculatiions in differntiation but this topic i dont understand

#340 Re: Help Me ! » Extreme values » 2017-03-09 01:24:37

yes its complete question its maxima and minima method

#341 Re: Help Me ! » Simple help of algebra » 2017-03-09 01:22:49

i calculate it but how squre root is sperate on.each value

#342 Re: Help Me ! » Simple help of algebra » 2017-03-09 00:05:53

How it leads to same result and show these lead to the same result.

#343 Re: Help Me ! » Extreme values » 2017-03-09 00:02:19

Hi all;
I have simple problem of this concept that is
If there is sqrt 2 divided by sqrt 9
Then how we say (2÷9)whole sqrt

#350 Re: Help Me ! » Logical question s » 2017-01-27 15:22:33

Hmm e^x at 1 is difficult to compute so which series used
