Gonna binge watch these new videos to hone my trig skills! Thank you, Prof!

When will linear algebra come out?? I'm dying out here in the wild.

Professor Leonard thank you for another great explanation of How to Use the Law of Cosines in Trigonometry. I also encountered the Law of Cosines/Sines in Statics, Dynamics and Engineering Physics I,II and III. Professor Leonard , a large C is used in the beginning of this video instead of a small c for the Law of Cosines. Please correct this error in the video.

I am Iraqi. Does he explain mathematics in Iraqi or English? ❤

[@felipaobravo6759]

English.

Hyperbolic trig should be part of precalculus. It's really not that bad. Not very many people noticed cosh is gamma.

I remember this because it looks like c^2=(a-b)^2 but the -2ab has cosC because this is law of cosine and there isn’t a C on the right side yet.

How many more videos of pre-calculus will still be coming, Professor Leonard?
