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

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

\frac{1}{8} (x - \frac{1}{4} sin (4 x)) + C

Solution steps

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

Rewrite using trig identities

= \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

= \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

= \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)

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

Add a constant to the solution

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

\frac{d}{d x} (\frac{π}{x ^{18}})

f (x) = 2 x^{3} - 6 x, at x = - 3

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

\int \frac{1}{3 - x ^{2} + 4 x} d x

f (t) = cos (t) + t sin (t)
