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

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..

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