The second one is correct, but not the first one. What you can say, though, is thatthis isn't homework just wanted to know what the values are.

tan -1 (infinity) = pi/2

tan-1 (0) = 0

lim(x -->infinity) tan

The domain of the inverse tangent function is all real numbers, but neither -infinity nor infinity is included in that set.

The domain for sinwhat is sin -1 infinty and cos -1 infinity?

Unline tan
