Question

Integrate the following expressions with respect to $x$. $\displaystyle\int \cos^2 (5x) - 1\, \mathrm{d}x$ $\int2 - \sin^2 (3x) \, \mathrm{d}x$ $\displaystyle\int \tan^2 (3x) \, \mathrm{d}x$

Accepted Answer

(a) $\frac1{20}\sin10x-\frac12x+C$. (b) $\frac32x+\frac1{12}\sin6x+C$. (c) $\frac13\tan3x-x+C$.
