Sum and Difference Formulas

[@meganterry3864]

SO helpful and the video isn’t unnecessarily long. Straight, to the point, and explained in a clear understandable way. MUCH appreciation to you!

[@jasonmcclendon8990]

I use your videos in stead of the ones provided by my math classes and they help me understand the concepts much faster.

Your method of converting to degrees makes so much sense and saves so much work. This is incomparable to my online professor's attempt at video for this lesson. Thank you for all you do, Saint Mario!

[@nickymujica7811]

thank you so much for this channel. Your videos are amazing and they’re very short but you do such a great job explaining things.

This might be the best video explaining how to find exact values using the sum and difference formula. Thank you Mario. It's super helpful and covers every detail.

[@MariosMathTutoring]

Glad it was helpful!

Thanks for the help, I would've probably been stuck staring at my homework problems for hours without this video!

[@erynvonhusen251]

Hello Mario, on your last example problem using tangent. For the sine of u which was -5/12 you just put 5/12. You corrected the cosv but not the sinv. I just wanted to point that out. Great video!

[@fly4lyf_213]

I'm also confused. He then changed the problem to sine u = 5/13, and puts 5/12 on the tan formula.

[@elysiaramsey3248]

so if the original is an addition will the right side sign be addition as well or is it flipped?
