I seriously love you, you taught me this better then my teacher did, and now that I’ve arrived at a correct answer I feel so proud

You make science very interesting, due to your tone's of examples representing real life situations, thanks very much sir, you're the best.

Does it matter the order you calculate? Like A -> B -> C or B-> A -> C?

Love the law of sine! Great video for sure!

Mr. Organic Chemistry Tutor, thank you for a solid analysis/introduction of The Law of Sines.

What is the difference between using this formula over a/SinA=b/SinB=c/SinC ?

LOVE YOUUU. YOU DESERVE ALL GOODS IN THE WORLD YOU HELP ME ALOTTTT PLEASE BE MY MATH TEACHER 😭😭😭❤️

[jmgroup]

Now I am confused. Is the law of sines formula sin A/a = Sin B/b = Sin C/c OR a/SinA = b/Sin B = c/Sin C

[murators]

Was waiting for this from you! Thank you!

Sir please please a video on faradays laws of electrolysis please look into this

my calculator is in degree mode but i keep getting a different answer and i even reset it then changed it to degree mode😭
