integral of cos(x)in(sin(x))

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

\frac{in}{2} sin^{2} (x) + C

Solution steps

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

Take the constant out:

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

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

Apply u-substitution

: \int u d u

= in \cdot \int u d u

Apply the Power Rule

: \frac{u ^{2}}{2}

= in \frac{u ^{2}}{2}

Substitute back

u = sin (x)

= in \frac{sin ^{2} ( x )}{2}

Simplify

in \frac{sin ^{2} ( x )}{2} : \frac{in}{2} sin^{2} (x)

= \frac{in}{2} sin^{2} (x)

Add a constant to the solution

= \frac{in}{2} sin^{2} (x) + C

\int 2 x^{2} + x d x

\int \frac{1}{1 + 2 x + 3} d x

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

\int \frac{5}{1 - x} d x

\int - 195 sin (7.8 x) d x
