integral of xsec^2(a)x

\int x sec^{2} (a) x d x

\frac{x ^{3} sec ^{2} ( a )}{3} + C

Solution steps

\int x sec^{2} (a) x d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= sec^{2} (a) \cdot \int xx d x

Simplify

xx : x^{2}

= sec^{2} (a) \cdot \int x^{2} d x

Apply the Power Rule

: \frac{x ^{3}}{3}

= sec^{2} (a) \frac{x ^{3}}{3}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{x ^{3} sec ^{2} ( a )}{3}

Add a constant to the solution

= \frac{x ^{3} sec ^{2} ( a )}{3} + C

\int x^{3} + x^{2} + x d x

\int 2 t - t^{2} d t

\int 6 tan^{2} (\frac{3 x}{4}) d x

\int \frac{1}{- 32 - 18 x - x ^{2}} d x

\int 12 y cos (4 x) d x
