Proof: Angle Sum/Difference Trig Identities (TAN)
Показать описание
In this video I will derive both the angle sum and angle difference identities for tangent. We will use the angle sum identities for SIN and COS derived in this video:
For my derivation of the angle difference identities for SIN and COS, check out this video:
For my derivation of the angle difference identities for SIN and COS, check out this video:
