I had this question on my final Calculus 2 exam. I am notquite sure if I this is the right answer :

My Answer :

## Answers ( 2 )

substituting x = t

^{2}we get dx = 2tdt

now our integral becomes ? 2t cos

^{2}t dt = ?t(1+cos2t)dt = ? (t +t cos2t)dtnow integrating using byparts i.e.

t

^{2}/2 + t?cos2tdt -=

CORRECT ANSWER IS

[(X/2)]+[{(?X)*SIN(2?X)}/2]+[{COS(2?X)}/4] +K

+K
