how would i find the integral of sin (2t+1)/cos^2(2t+1) dt

math 
Damon
let u = (2t+1)
du = 2 dt so dt = .5 du
so
.5 integral du sin u/cos^2u
try 1/cos u
d/du (1/cos u) = sin u/cos^2 u
You can take it from there :)

That's the same as the integral of sin^2 x dx. Use integration by parts. Let sin x = u and sin x dx = dv v = cos x du = cos x dx The integral is u v  integral of v du = sinx cosx + integral of cos^2 dx which can be rewritten integral …
