integral of 6sin^2(x)

\int 6 sin^{2} (x) d x

3 (x - \frac{1}{2} sin (2 x)) + C

Solution steps

\int 6 sin^{2} (x) d x

Take the constant out:

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

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

Rewrite using trig identities

= 6 \cdot \int \frac{1 - cos ( 2 x )}{2} d x

Take the constant out:

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

= 6 \cdot \frac{1}{2} \cdot \int 1 - cos (2 x) d x

Apply the Sum Rule:

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

= 6 \cdot \frac{1}{2} (\int 1 d x - \int cos (2 x) d x)

\int 1 d x = x

\int cos (2 x) d x = \frac{1}{2} sin (2 x)

= 6 \cdot \frac{1}{2} (x - \frac{1}{2} sin (2 x))

Simplify

6 \cdot \frac{1}{2} (x - \frac{1}{2} sin (2 x)) : 3 (x - \frac{1}{2} sin (2 x))

= 3 (x - \frac{1}{2} sin (2 x))

Add a constant to the solution

= 3 (x - \frac{1}{2} sin (2 x)) + C

\frac{d}{d x} (11 sec^{2} (x))

c y^{- 5}

\frac{\partial}{\partial y} (6 x z sin (y))

\frac{d}{d x} (\frac{2 x}{8})

\frac{d}{d x} (- \frac{200}{x ^{2}})
