Question

integration x^2/1-x^4​

Answer 1

Answer:

generally how many types of account can be be opened in a bank?

Answer 2

Step-by-step explanation:

I=x^2 /(1-x^4)

=1/2[2x^2 /(1-x^4)]

=1/2[{(1+x^2)-(1-x^2)}/(1-x^4)]

=1/2[(1+x^2)/(1-x^4) -(1-x^2)/(1-x^4)]

=1/2[(1+x^2)/(1+x^2)(1-x^2) -(1-x^2)/(1+x^2)(1-x^2)]

=1/2[1/(1-x^2) -1/(1+x^2)]

Now integrate

I=1/2[1/2 ln|(1+x)/(1-x)| -arctan(x)] +C

Hope it helps you.
