Homework Help: Math

Posted by emath on Tuesday, February 23, 2010 at 10:10pm.

integrate (sinx)^(5)(cosx)^(12)from 0 to (pi/2)

I'm having problems just even integrating it...
I tried breaking it up
(sin^(2)x)^(2)(cos^(2)x)^(6)(sinx)dx
then doing u-sub with u=cosx and du= -sinx
but then I get stuck...
the answer is 8/3315 just don't know how to get that answer!
