integrate sin x cos x dx





cos x dx sin x C Proof.csc2 x dx - cot x C Proof. Inverse Trigonometric. I just noticed that you have cos(x) raised to some power, and that the derivative of cosine is - sin(x), so I did the "chain rule" in reverse. Somebody else answered (1/2)tan( x) c, which is not wrong. If you use the fact that sin2 (x) cos2(x) 1, and apply it to the other answer The only thing that youre doing wrong is forgetting the constant of integration: your two antiderivatives differ by a constant, so of course they are antiderivatives of the same function.
