integral of cot(1/2)x

\int cot (\frac{1}{2}) x d x

\frac{1}{2} cot (\frac{1}{2}) x^{2} + C

Solution steps

\int cot (\frac{1}{2}) x d x

Take the constant out:

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

= cot (\frac{1}{2}) \cdot \int x d x

Apply the Power Rule

: \frac{x ^{2}}{2}

= cot (\frac{1}{2}) \frac{x ^{2}}{2}

Simplify

cot (\frac{1}{2}) \frac{x ^{2}}{2} : \frac{1}{2} cot (\frac{1}{2}) x^{2}

= \frac{1}{2} cot (\frac{1}{2}) x^{2}

Add a constant to the solution

= \frac{1}{2} cot (\frac{1}{2}) x^{2} + C

\int \frac{θ ^{3}}{9 - θ ^{2}} d θ

\int \frac{d}{d x} (x^{2}) d x

\int \frac{2 x + 1}{3 x ^{2} + 8 x - 1} d x

\int \frac{1}{x ( ln ( x ^{2} ) ) ^{9}} d x

\int \frac{4}{( 2 x - 1 )} d x
