Question

Stuck on an integral while solving a DEQ. (Please see attached).

Answer 1

\[-2 \int\limits \frac{1}{x^2-1} \, dx\]

Answer 2

HI!!

Answer 3

partial fractions after writing as
\[\frac{a}{x+1}+\frac{b}{x-1}\]

Answer 4

you should get
\[\int \frac{1}{2(x-1)}dx-\int \frac{1}{2(x+1)}dx\]

Answer 5

Aaaah. I guess that proves that getting good grades in calculus wasn't enough. I actually have to use it. :)

Answer 6

That was it, thank you!
