integral of 6cos(x)sin(x)

\int 6 cos (x) sin (x) d x

3 sin^{2} (x) + C

Solution steps

\int 6 cos (x) sin (x) d x

Take the constant out:

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

= 6 \cdot \int cos (x) sin (x) d x

Apply u-substitution

= 6 \cdot \int u d u

Apply the Power Rule

= 6 \cdot \frac{u ^{2}}{2}

Substitute back

u = sin (x)

= 6 \cdot \frac{sin ^{2} ( x )}{2}

Simplify

6 \cdot \frac{sin ^{2} ( x )}{2} : 3 sin^{2} (x)

= 3 sin^{2} (x)

Add a constant to the solution

= 3 sin^{2} (x) + C
