integral of (1-t^2)^3

integral

(1 - t^{2})^{3}

t - t^{3} + \frac{3 t ^{5}}{5} - \frac{t ^{7}}{7} + C

Solution steps

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

Expand

(1 - t^{2})^{3} : 1 - 3 t^{2} + 3 t^{4} - t^{6}

= \int 1 - 3 t^{2} + 3 t^{4} - t^{6} d t

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 1 d t - \int 3 t^{2} d t + \int 3 t^{4} d t - \int t^{6} d t

\int 1 d t = t

\int 3 t^{2} d t = t^{3}

\int 3 t^{4} d t = \frac{3 t ^{5}}{5}

\int t^{6} d t = \frac{t ^{7}}{7}

= t - t^{3} + \frac{3 t ^{5}}{5} - \frac{t ^{7}}{7}

Add a constant to the solution

= t - t^{3} + \frac{3 t ^{5}}{5} - \frac{t ^{7}}{7} + C

\frac{5 x ^{4}}{x ^{5} + 9}

x \cdot lo g_{10} (\frac{1}{x})

\frac{1}{( x ( ln ( x ) ) )}

u^{- 1}

\frac{( x ) ^{\frac{1}{2}}}{( a - x ) ^{\frac{1}{2}}}
