integral of (sec^2(x)-7)

\int (sec^{2} (x) - 7) d x

tan (x) - 7 x + C

Solution steps

\int sec^{2} (x) - 7 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 7 d x

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

\int 7 d x = 7 x

= tan (x) - 7 x

Add a constant to the solution

= tan (x) - 7 x + C
