Question

If possible, find the exact value of sin^-1(2)

Answer 1

Assuming this is in radians, that is the exact value.

Answer 2

Ok. Could you tell me how 2 is the exact value?

Answer 3

well...
\[\sin^{-1}(2)\]
is a transcendental number (a decimal with no repetition) so that is the exact version, because it cant be simplified/factored.

Answer 4

Understood. Do you know of any websites that can help me with exact values?
