# Thread: [Help] problem with antiderivatives and substitution

1. ## [Help] problem with antiderivatives and substitution

hi guys Good day, please help me to solve my problem. This will be my reviewer in my prelims. i have an answer in antiderivatives but I am not sure. In substitution , I am having a hard time in solving that one problem. PLease show me your solution. thanks

ANTIDERIVATIVES

SUBSTITUTION

2. ## Re: [Help] problem with antiderivatives and substitution

For the first one, I would write the result as:

$2\left(\ln|x|-\frac{1}{x} \right)+C$

The second integral is an elliptic integral. Are you sure it is copied correctly?

edit: a point that might coist you marks on an exam...you are omitting the differentials from your integrals.

yeah,, im very sure, i had copy it correctly. can you show me your solution to my first question? thanks

4. ## Re: [Help] problem with antiderivatives and substitution

I wrote in my first post how I would express the anti-derivative. You could also write it as:

$\ln(x^2)-\frac{2}{x}+C$
