First make a substitution and then use integration by parts to evaluate the integral. integral t^11 e^-t^6 dt + C

It looks like you want to find

Substitute u = -t ⁶ and du = -6t ⁵ dt. Then

Integrate by parts, taking

f = u   ==>   df = du

dg = eᵘ du   ==>   g = eᵘ

Then

0.02040816326

the correct answer is c

good luck love
