Hello, sigma1!
I'll do the derivation . . .
Using the identity , find a reduction formula for the integral:
. .
We have: .
. . . . .
. . . . .
. . . . .
. . . . .
. . . . .
Therefore: .
using the identity find a reduction formula for the integral where n is greater than or equal to 2
hence evaluate from 0 to pie/4 ( cant really type this in the mathematical terms.
ok to express this in reduction form i made
(for the identity)
then substituted it in the expression
did i do it right? and if so how would that help me to evaluate the integral.
