\int {c o s}^{6} x \times c o s x d x

\int {(1 - {s i n}^{2} x)}^{3} \times c o s x d x

\int {(1 - a^{2})}^{3} d a

\int (1 - 3 a^{2} + 3 a^{4} - a^{6}) d a

a - a^{3} + \frac{3 a^{5}}{5} - \frac{a^{7}}{7} + c

s i n x - \frac{{s i n}^{3} x}{1} + \frac{3 {s i n}^{5} x}{5} - \frac{{s i n}^{7} x}{7} + c
