Why is any integral the way it is? Integrals are antiderivatives. Any statement about integrals can be rewritten as a statement about derivatives.Okay, well, you probably know that: d/dx [cos(x)] -sin(x). Question from matt, a student: how does sin2x break down (not with identities) and how would sin3 x be created.

integral of cos2xtan3x, calculus, stewart calculus solution, steve chow pierce college Integrate sin(8x) cos(5x) dx. integrating powers of a variable tells you to increase the power by 1 and then divide by the new power. In the integral given by Equation (1) there is still a power 5, but the integrand is more complicated due to the presence of the term x 4. To tackle this problem we make a substitution.x4(1 x5)3dx. 217. THINK. 5 Substitute u for loge4x and x du for dx in the integral. 6 Cancel out x. 7 Antidifferentiate with respect to u. 8 Replace u by loge4x. d 1 Express cos3 x as cos x cos2x. 1-- sin3x 1-- sin5x c.
