A more powerful version of the Sine Law.

The extended Sine Law is way more interesting than the one we learn in school. In this video we explain what it is and we prove it using Thales's circle theorem and some trigonometry.

Genial la explicación y el video

Thank you very much!

can you teach me more of what you did to find sin(180-x)? like other more difficult variations such as sin(70pi/2-x) plzz 🙏

[@tedszy7100]

sin(x) is odd so sin(-x) = -sin(x). So then sin(pi-x) = -sin(x-pi). Take the plot of sin(x) and flip it over x-axis. This is now -sin(x). Now shift the origin to the LEFT by pi. With origin in the new place you see your plot is now sin(x).
