integral of (7+tan^2(θ))

\int (7 + tan^{2} (θ)) d θ

6 θ + tan (θ) + C

Solution steps

\int 7 + tan^{2} (θ) d θ

Apply the Sum Rule:

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

= \int 7 d θ + \int tan^{2} (θ) d θ

\int 7 d θ = 7 θ

\int tan^{2} (θ) d θ = - θ + tan (θ)

= 7 θ - θ + tan (θ)

Simplify

= 6 θ + tan (θ)

Add a constant to the solution

= 6 θ + tan (θ) + C
