Question

How would I solve this integral?

Answer 1

\[\int\limits \frac{dx}{(z^2+x^2)^{3/2}}\]

Answer 2

First, what's \(z\)? complex number?

If not, \(x=sinh(u)\) might work.

Answer 3

z is just any constant.

Answer 4

Then \(x=sinh(u)\)!
or \(x=tan(u)\)

Answer 6

or you can use hyperbolic; dependent on you!

Answer 7

ok, ot it. Ty

Answer 8

Answer 9

:) which substution did you use?

Answer 10

trig

Answer 11

ok, the hyperbolic sub..might me easier at times tho!
