Question

integrate cos (sqrt x) dx

Answer 1

\[\int\limits_{}^{} \cos \sqrt{x} dx\]

Answer 2

I got:\[2(\sqrt{x}\sin(\sqrt{x})+\cos(\sqrt{x}))\]Do you need an explanation or were you just checking an answer?

Answer 3

ca you explain? :)

Answer 4

let u = sqrt(x)
x = u^2
dx = 2u du

cos(u) * 2u du

now just use integration by parts

Answer 5

yeah i already get it. thanks. :D
