Don't always pick what you think is the most complicated side
Not always do we need to simplify the most complicated side. In this example I show you why that is the case βοΈ Don't get rid of your denominators, combine them - β’ Don't get rid of your denominators, c... π₯Verifying trigonometric...

which side should you pick to verify the identity?
One of the harder things for students to be able to complete is decide which side they need to simplify first when verifying an identity. In this video I try to tackle that. β I go against using the most complicated side - β’ Don't always...
