Channel: MathHub TV
Date: 2022-01-24

In this trigonometry lecture, I will be proving trigonometric identities.  How do we prove trigonometric identities?  To prove trigonometric identities, I will be using the following strategies:
a.  Algebraic Methods - factoring, multiplying both numerator and denominator by the same expression
b.  Using fundamental identities 
c.  Expressing both sides of the expression in terms of sine and cosine function only
