integral of tan(x)+sec^2(x)

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

- ln ∣ cos (x) ∣ + tan (x) + C

Solution steps

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

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

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

\int tan (x) d x = - ln ∣ cos (x) ∣

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

= - ln ∣ cos (x) ∣ + tan (x)

Add a constant to the solution

= - ln ∣ cos (x) ∣ + tan (x) + C

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

\int (10 x + 2) d x

\int cos (\frac{2 x}{5}) d x

\int \frac{1}{51 - 70 x - 25 x ^{2}} d x

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