WHAT IS COS 90
The cosine is the adjacent over the hypotenuse.
90o would make the hypotenuse be pointing straight up.
Call its length "infinite" although infinity is not a number.
finite number
Anyway cos(90) would be –––––––––– = ZERO
infinite
I've broken every rule in the book against using
infinity as a number, but I did it only to illustrate
how to visualize a trigonometric function as the
ratio of two sides of a right triangle.

+40 Haha! Love how confident this explanation. Cos(90) in right triangle trig literally just destroys the concept of a triangle lol

@SoulKingBrook < destroys the concept of a triangle >
LOL, I was afraid I'd get my hand slapped for
taking liberties with the concept of infinity.
But wait. Using the proposition that in infinity,
not only are all things possible, but all things
are inevitable.
Just as parallel lines drawn northward on the
earth's surface do converge at the north pole,
might not the parallel lines in the example of
this problem converge at infinity? And thus
preserving the trianglature?
