Question

The domain of function Tan-1 a = θ is restricted to
A) {a | -1 ≤ a ≤ 1}
B) {a | -∞ ≤ a ≤ ∞}
C) {a | -90º ≤ a ≤ 90º}

Answer 1

What do you think @georgejafacules

Answer 2

Not really sure because I don't understand this stuff

Answer 3

you know the values of tan(theta) lies between which interval?

Answer 4

domain of tan inverse is range of tan which is +infinity to -inifinty
