- 👉 Learn how to verify trigonometric identities having rational expressions. To verify trigonometric expression means to verify that the terms on the left-hand side of the equality sign is equal to the terms on the right-hand side. To verify rational trigonometric identities, it is usually more convenient to start with getting rid of the denominator(s) of the rational term(s). This can be done by multiplying both the numerator and the denominator by the conjugate of the denominator, if the denominator involves addition/subtraction or by the reciprocal of the denominator, if the denominator involves product or the expression can be converted to Pythagoras trigonometric identity if possible.

8 years later and this dude single handedly saves my precal career
really happy to help,
My math teacher is the best. But whenever I don’t understand something in class I know you’ll help me understand 🥱 thank youuuuuuuuu
just wanted to let you know that your videos helped me so much in my trigonometry class this is the only thing that actually helped me understand this.
This was very helpful. I had been absent for the lesson on identities and this helped me understand it a lot. Thank you!
Hey man I really appreciate you posting these my teacher is really hard to understand and I really struggle with proofs and your a big help
Who’s here because of coronavirus
i go to a overcrowded school so it’s hard for my teacher to make sure everyone’s caught up, your videos help me not get left behind! thanks!
