## Homework Statement

I have to solve this integral

S cos(x^1/2)dx

where S is the integral symbol

## Homework Equations

## The Attempt at a Solution

the book tells me to use substitution and then integrate by parts

so i say u = x^1/2

du = 1/2*x^-1/2

then i can write 2 S (cos(u)du)/ x^1/2

where S in the integral sign

from here i think i can substitute the x^1/2 in the denominator by u because of the definition u = x^1/2

after the last substitution my integral would look like 2 S cos(u)/u

is this even close to right
