One more thing about trigonometry. One needs to remember that triangles with angles
90-30-60 and 90-45-45 have their sides related to each other as 2:sqrt3:1 and sqrt2:1:1

But this is basic geometry, in my opinion.
I referred to trigonometric formulas as those involving sin,cos,etc.
Anyways, it is absolutely futile to discuss what is trigonometry!
