integral of sec^2(x)csc^2(x)

\int sec^{2} (x) csc^{2} (x) d x

- 2 cot (2 x) + C

Solution steps

\int sec^{2} (x) csc^{2} (x) d x

Rewrite using trig identities

= \int \frac{8}{1 - cos ( 4 x )} d x

Take the constant out:

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

= 8 \cdot \int \frac{1}{1 - cos ( 4 x )} d x

Apply u-substitution

: \int \frac{1}{4 ( 1 - cos ( u ) )} d u

= 8 \cdot \int \frac{1}{4 ( 1 - cos ( u ) )} d u

Take the constant out:

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

= 8 \cdot \frac{1}{4} \cdot \int \frac{1}{1 - cos ( u )} d u

Apply u-substitution

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

= 8 \cdot \frac{1}{4} \cdot \int \frac{1}{v ^{2}} d v

Apply the Power Rule

: - \frac{1}{v}

= 8 \cdot \frac{1}{4} (- \frac{1}{v})

Substitute back

= 8 \cdot \frac{1}{4} (- \frac{1}{tan ( \frac{4 x}{2} )})

Simplify

8 \cdot \frac{1}{4} (- \frac{1}{tan ( \frac{4 x}{2} )}) : - 2 cot (2 x)

= - 2 cot (2 x)

Add a constant to the solution

= - 2 cot (2 x) + C

\int_{0}^{\infty} e^{- x t} d t

\int 16 t^{3} d t

\int_{\frac{1}{2}}^{7} 10 x ln (2 x) d x

\int_{0}^{4} 3 e^{- x^{2}} d x

f (x) = 9
