Question

integral of sin(x)cos(x)e^(sin(x)^2)

Answer 1

by u-substitution i get

ue^u^2du and fro there i have no idea how to continue

Answer 2

Do another u sub where you let w=u^2, .5dw=udu -> you'll have e^w dw

Answer 3

You could also just use trig identities [ sin2x=2sinxcosx and sin^x = .5(1-cos2x) ] to change the original problem and do a normal single u-sub of the part that e is raised to (if you wanted)

Answer 4

for this problem im not allowed to use trig identities

Answer 5

thanks a lot. i was able to solve it :D
