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

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

tan (x) - ln ∣ cos (x) ∣ + C

Solution steps

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

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

\int tan (x) d x = - ln ∣ cos (x) ∣

= tan (x) - ln ∣ cos (x) ∣

Add a constant to the solution

= tan (x) - ln ∣ cos (x) ∣ + C
