integral of sin^2(x+2)

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

\frac{1}{2} (x - \frac{1}{4} sin (4 x)) + C

Solution steps

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

Rewrite using trig identities

= \int 4 cos^{2} (x) sin^{2} (x) d x

Take the constant out:

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

= 4 \cdot \int cos^{2} (x) sin^{2} (x) d x

Rewrite using trig identities

= 4 \cdot \int \frac{1 - cos ( 4 x )}{8} d x

Take the constant out:

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

= 4 \cdot \frac{1}{8} \cdot \int 1 - cos (4 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

= 4 \cdot \frac{1}{8} (\int 1 d x - \int cos (4 x) d x)

\int 1 d x = x

\int cos (4 x) d x = \frac{1}{4} sin (4 x)

= 4 \cdot \frac{1}{8} (x - \frac{1}{4} sin (4 x))

Simplify

4 \cdot \frac{1}{8} (x - \frac{1}{4} sin (4 x)) : \frac{1}{2} (x - \frac{1}{4} sin (4 x))

= \frac{1}{2} (x - \frac{1}{4} sin (4 x))

Add a constant to the solution

= \frac{1}{2} (x - \frac{1}{4} sin (4 x)) + C

\int 144 - t^{2} d t

\int_{0}^{5} (2 e^{x} + 4 cos (x)) d x

x \to 2 - lim (\frac{3 x}{x ^{2} - 4})

\frac{d}{d x} (\frac{e ^{x}}{3 x ^{2} + 2 x ^{4}})
