Trigonometric identities and homer measuring trees
Posted by ricardogm on January 21st, 2019
Hi
We are going to prove these two famous trigonometic identities:
sin2(x) + cos2(x) = 1
tan(x)=cos(x)/sin(x)
that can be seen in this applet:
And how to measure trees with trigonometry (we are going to do more or less the same thing):
