Example In (tan^2)x your 1st mistake is not writing dx. Note that dx is NOT always du!!!!! If you let u=tanx in integral (tan^2)x you get integral u^2 dx which is not (u^3)/3 + c since du= sec^2x dx [math]I = \int x \ tan^2(x) dx[/math] Taking advantage of the fact that [math]tan^2(x) = sec^2(x) - 1[/math], [math]I = \int \left[ x \ sec^2(x) - x \right] dx[/math Integrals with Trigonometric Functions Z sinaxdx= 1 a cosax (63) Z sin2 axdx= x 2 sin2ax 4a (64) Z sinn axdx= 1 a cosax 2F 1 1 2; 1 n 2; 3 2;cos2 ax (65) Z sin3 axdx= 3cosax 4a + cos3ax 12a (66) Z cosaxdx= 2011-10-25 · 1/3 tan(3x) - x + C. 1 0.
