integral of sec^3(β)

\int sec^{3} (β) d β

\frac{1}{2} sec (β) tan (β) + \frac{1}{2} ln ∣ tan (β) + sec (β) ∣ + C

Solution steps

\int sec^{3} (β) d β

Apply Integral Reduction

= \frac{sec ^{2} ( β ) sin ( β )}{2} + \frac{1}{2} \cdot \int sec (β) d β

\int sec (β) d β = ln ∣ tan (β) + sec (β) ∣

= \frac{sec ^{2} ( β ) sin ( β )}{2} + \frac{1}{2} ln ∣ tan (β) + sec (β) ∣

Simplify

\frac{sec ^{2} ( β ) sin ( β )}{2} + \frac{1}{2} ln ∣ tan (β) + sec (β) ∣ : \frac{1}{2} sec (β) tan (β) + \frac{1}{2} ln ∣ tan (β) + sec (β) ∣

= \frac{1}{2} sec (β) tan (β) + \frac{1}{2} ln ∣ tan (β) + sec (β) ∣

Add a constant to the solution

= \frac{1}{2} sec (β) tan (β) + \frac{1}{2} ln ∣ tan (β) + sec (β) ∣ + C
