so the integral of sinx.cosx = 0.5sin^2(x) by the substitution method,
and the integral by changing sinxcosx to 0.5sin2x = -0.25(cos(2x)) .
however these do not equal each other and I can not seem to change one into the either using my trig knowledge.
Please can someone show that one equals the other?
