integral of 2^{2x}tan(2^x)sec^2(2^x)

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

\frac{1}{ln ( 2 )} (2^{x - 1} tan^{2} (2^{x}) - \frac{1}{2} (- 2^{x} + tan (2^{x}))) + C

Solution steps

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

Apply u-substitution

= \int \frac{u sec ^{2} ( u ) tan ( u )}{ln ( 2 )} d u

Take the constant out:

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

= \frac{1}{ln ( 2 )} \cdot \int u sec^{2} (u) tan (u) d u

Apply Integration By Parts

= \frac{1}{ln ( 2 )} (\frac{1}{2} u tan^{2} (u) - \int \frac{1}{2} tan^{2} (u) d u)

\int \frac{1}{2} tan^{2} (u) d u = \frac{1}{2} (- u + tan (u))

= \frac{1}{ln ( 2 )} (\frac{1}{2} u tan^{2} (u) - \frac{1}{2} (- u + tan (u)))

Substitute back

u = 2^{x}

= \frac{1}{ln ( 2 )} (\frac{1}{2} \cdot 2^{x} tan^{2} (2^{x}) - \frac{1}{2} (- 2^{x} + tan (2^{x})))

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

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

Add a constant to the solution

= \frac{1}{ln ( 2 )} (2^{x - 1} tan^{2} (2^{x}) - \frac{1}{2} (- 2^{x} + tan (2^{x}))) + C

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

\int cos (3 x) cos (2 x) 2 d x

\int 32 (8 x + 7)^{3} d x

\int \frac{x ^{4} + 81}{x ( x ^{2} + 9 ) ^{2}} d x

in t e g r a l x^{- \frac{1}{2}}
