integral of sin^2(x/4)cos^2(x/4)

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

\frac{1}{8} (x - sin (x)) + C

Solution steps

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

Rewrite using trig identities

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

Take the constant out:

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

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

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

\int 1 d x = x

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

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

Add a constant to the solution

= \frac{1}{8} (x - sin (x)) + C

\int \frac{sin ( arctan ( x ) )}{1 + x ^{2}} d x

\int \frac{3}{3 x - 1} d x

\int 5 x ln (x) d x

\int \frac{x ^{2}}{2} e^{x} d x

\int \frac{x + 5}{x ^{2} - 6 x + 3} d x
