To verify a trig function means to prove the left side if it is correct while not touching the right side. We must prove it is correct because we use our identities to prove them right.
2.I had to memorize the identities because this is what will help us throughout the unit. Another tip.is to.look for identities that we can replace with and have the same . Like sin for the whole equation
3.I start by looking at the left side . I dont touch the right side. We look if we can substitute a identity or reciprocal. We get a a common denominator or gcf. We do all we need to get our answer on the left. This includes several key factors that will help us achieve our proven equation.
