i was looking at okeanskiy’s video about rotating head along with the camera rotation. I was getting everything until he involved the math.asin and stuff like that. is anyone able to draw like a diagram to show how it works, and how a triangle is involved?

He uses the Opposite & Hypotenuse, divides them by eachother and uses the formula.

`sin(a) = O/H`

`a = arcsin(O/H)`

How would this be applied as a triangle though? like in reference with the video, where would the 90 degree angle be, and the angles that we are trying to find and such. i just don’t get how a triangle can be applied in this situation.
