Question

what is the indefinite integral of (1)/(1 + 4x^2) ?

Answer 1

first have you guys learned u substitution yet

Answer 2

We have, but I can only do it when the constant in front of the x^c value = 1. Even then, i'm rusty. I was hoping for an example, that is if you don't mind providing one.

Answer 3

i can show you an example of u sub

Answer 4

oh, sorry. I was thinking a trig sub was needed

Answer 5

so you dont need an example anymore?

Answer 6

Maybe not, assuming I can do it with a simple u sub.

Answer 7

basically were going to set the denominator equal to u

Answer 8

yeah, but then u^-1 ... you can't integrate that.

Answer 9

I mean you can, but
