Question

What does `2sin(arccos(3))+3tan(arcsin(5))` equal?

Answer 1

arc cos 3 and arc sin 5 are invalid arc cosine and arc sin. values..

Explanation:

As any cosine value `in[-1. 1]`. 3 is out of bounds, and so,

arc cos 3 ( the angle whose cosine is 3) is invalid.

Likewise, arc sin 5 is also invalid..
