Law of Sines and Law of Cosines (4 Examples)

[@rooftoptrading461]

Mr Mario. as a dad who forgot all his math I have to thank you for putting this together. It makes helping my kids a breeze. Thank you.

[@MariosMathTutoring]

Awesome! Thanks for letting me know! Glad my videos can help your family out!

Sir, you are great teacher Because unlike any youtube tutorial videos your voice is loud and clear, your examples are brilliant and The best of all it's completely free... Thank you so much Sir You were such a big help for me

[@klasrem]

This video is a life saver. I want to say you taught this in a much easier to understand way than my teacher did in a week. Granted, I didn't pay much attention on Sines, but I did with Cosines, and I now have a clear understanding of both. My teacher never mentioned anything about Cosines being used on SSS and SAS triangles. You have a really good way of teaching this stuff. Good job!

[@MariosMathTutoring]

Glad it helped!

[@neodong6060]

Mario's explanations and examples are amazing. He makes learning the material so many times easier, and the fact that he's doing this for free and out of the good of his heart is amazingly gracious. He's the math teacher we all wanted, but didn't deserve. Someone give him a cinnabon

My guy this was perfect timing I just learned this today. THANK YOU SO MUCH

2:02 why did u multiply by 6, is there any other way to solve without multiplying by 6?

[@MariosMathTutoring]

You want to get the sinC by itself….another option is to cross multiply to get rid of the fractions. Hope that helps!

[@vkaygee]

@@MariosMathTutoring how did you get the .805 and what did you multiply to get 53.7?

[@son-ce3gr]

hey what if you’re given a triangle without labeling sides ABC respectively and there’s a missing angle at the top?

[@CookiehsAndDreams]

I might be a little late on this and I don't fully understand it either, but if you have the angles of the other two sides, you should be able to just subtract those two angles from 180, you should be able to get the missing angle. I might be wrong, but I hope I could help a little!
