integral of 1/((1-cos(x)))

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

- cot (\frac{x}{2}) + C

Solution steps

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

Apply u-substitution

: \int \frac{1}{u ^{2}} d u

= \int \frac{1}{u ^{2}} d u

Apply the Power Rule

: - \frac{1}{u}

= - \frac{1}{u}

Substitute back

u = tan (\frac{x}{2})

= - \frac{1}{tan ( \frac{x}{2} )}

Use the basic trigonometric identity:

\frac{1}{tan ( x )} = cot (x)

= - cot (\frac{x}{2})

Add a constant to the solution

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

\int \frac{( arctan ( 9 x ) )}{1 + 81 x ^{2}} d x

\int tan (t^{2}) d t

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

\int 2 z sin (2 z) - cos (2 z) d z

\int cos (x) \cdot cos (n x) d x
