*WHAT IS COS 90*

The cosine is the adjacent over the hypotenuse.

90^{o} 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.

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?
