Question

evaluate the integral 1/(x^(2)sqrt(4-x^(2))

Answer 1

Is this what you intend?\[\int \dfrac{dx}{x^2 \sqrt{4-x^2}}\]

Answer 2

yes :)

Answer 3

Try the substitution:\[x=2\sin u\]

Answer 4

yes :)

Answer 5

ok :) let me try it from here

Answer 6

yes :)

Answer 7

ok so i got it simplified down to: \[\int\limits_{?}^{?}1\div \sin ^{2}xcosx du \]

Answer 8

do i do a u subsitution?

Answer 9

You forgot that\[dx = 2\cos u \text{ } du\]
