integral of 3sin^2(x)cos(x)

\int 3 sin^{2} (x) cos (x) d x

sin^{3} (x) + C

Solution steps

\int 3 sin^{2} (x) cos (x) d x

Take the constant out:

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

= 3 \cdot \int sin^{2} (x) cos (x) d x

Apply u-substitution

: \int u^{2} d u

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

Apply the Power Rule

: \frac{u ^{3}}{3}

= 3 \cdot \frac{u ^{3}}{3}

Substitute back

u = sin (x)

= 3 \cdot \frac{sin ^{3} ( x )}{3}

Simplify

3 \cdot \frac{sin ^{3} ( x )}{3} : sin^{3} (x)

= sin^{3} (x)

Add a constant to the solution

= sin^{3} (x) + C

f (x) = \frac{e ^{x}}{x ^{2}}

\frac{d}{d x} (x - cos (y))

\frac{6}{( s - 2 ) ^{4} \cdot ( s + 2 ) ^{2}}

\int x^{7} - 3 x + 2 d x
