integral of (1-cos^2(x))sin(x)

\int (1 - cos^{2} (x)) sin (x) d x

- cos (x) + \frac{cos ^{3} ( x )}{3} + C

Solution steps

\int (1 - cos^{2} (x)) sin (x) d x

Apply u-substitution

: \int - 1 + u^{2} d u

= \int - 1 + u^{2} d u

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 u + \int u^{2} d u

\int 1 d u = u

\int u^{2} d u = \frac{u ^{3}}{3}

= - u + \frac{u ^{3}}{3}

Substitute back

u = cos (x)

= - cos (x) + \frac{cos ^{3} ( x )}{3}

Add a constant to the solution

= - cos (x) + \frac{cos ^{3} ( x )}{3} + C

\int 11 sec^{- 2} (x t a) n^{3} x d x

\frac{\partial}{\partial x} (y e^{x} + x e^{- y})

\frac{1}{( 7 + x ) ^{2}}

y = \frac{4 x}{x ^{2} + 1}, (1, 2)
