integral of (tan(x))/(sqrt(sec^2(x)-4))

\int \frac{tan ( x )}{sec ^{2} ( x ) - 4} d x

\frac{1}{2} arcsec (\frac{1}{2} sec (x)) + C

Solution steps

\int \frac{tan ( x )}{sec ^{2} ( x ) - 4} d x

Apply u-substitution

: \int \frac{1}{u u ^{2} - 4} d u

= \int \frac{1}{u u ^{2} - 4} d u

Apply Trigonometric Substitution

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

= \int \frac{1}{2} d v

Take the constant out:

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

= \frac{1}{2} \cdot \int 1 d v

Integral of a constant:

\int a d x = a x

= \frac{1}{2} \cdot 1 \cdot v

Substitute back

= \frac{1}{2} \cdot 1 \cdot arcsec (\frac{1}{2} sec (x))

Simplify

= \frac{1}{2} arcsec (\frac{1}{2} sec (x))

Add a constant to the solution

= \frac{1}{2} arcsec (\frac{1}{2} sec (x)) + C

\int \frac{x}{6 x - x ^{2} - 4} d x

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

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

\int \frac{x ^{2} + x - 10}{( 2 x - 3 ) ( x ^{2} + 4 )} d x

\int \frac{5 x - 3}{18 x ^{3} - 60 x ^{2} + 50 x} d x
