integral of 7θsec^2(θ)

\int 7 θ sec^{2} (θ) d θ

7 (θ tan (θ) + ln ∣ cos (θ) ∣) + C

Solution steps

\int 7 θ sec^{2} (θ) d θ

Take the constant out:

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

= 7 \cdot \int θ sec^{2} (θ) d θ

Apply Integration By Parts

= 7 (θ tan (θ) - \int tan (θ) d θ)

\int tan (θ) d θ = - ln ∣ cos (θ) ∣

= 7 (θ tan (θ) - (- ln ∣ cos (θ) ∣))

Simplify

= 7 (θ tan (θ) + ln ∣ cos (θ) ∣)

Add a constant to the solution

= 7 (θ tan (θ) + ln ∣ cos (θ) ∣) + C
