How to evaluate the indefinite integral tanΘdΘ | Integrate tan(x) | calculus | Indefinite Integrals

In this video I explain how to evaluate the indefinite integral tan(Θ)dΘ,
∫tanΘdΘ.


I demonstrate how to use a trig identity to replace tan(Θ) and create a function that is more easily integrated. I then
evaluate the integral using U-Substitution.
