integral of (10)/(1-cos(2x))

\int \frac{10}{1 - cos ( 2 x )} d x

- 5 cot (x) + C

Solution steps

\int \frac{10}{1 - cos ( 2 x )} d x

Take the constant out:

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

= 10 \cdot \int \frac{1}{1 - cos ( 2 x )} d x

Rewrite using trig identities

= 10 \cdot \int \frac{1}{2 sin ^{2} ( x )} d x

Take the constant out:

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

= 10 \cdot \frac{1}{2} \cdot \int \frac{1}{sin ^{2} ( x )} d x

Use the common integral:

\int \frac{1}{sin ^{2} ( x )} d x = - cot (x)

= 10 \cdot \frac{1}{2} (- cot (x))

Simplify

10 \cdot \frac{1}{2} (- cot (x)) : - 5 cot (x)

= - 5 cot (x)

Add a constant to the solution

= - 5 cot (x) + C

f (x) = x^{2} - 4 x y + y^{2} = 4

\int_{1}^{3} 17 x^{3} ln (x) d x

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

\int \frac{y - 3}{y - 2} d y

\int e^{x + 4} d x
