Trigonometry
If y = f(x) and x = g(y) are two functions such that f (g(y)) = y and g (f(y)) = x, then f and y are said to be ___________ of each other.

a) Derivative
b) Product
c) Inverse
d) Integration



Answer
Correct Answer Is : Inverse
Solution Is :
If y = f(x) and x = g(y) are two functions such that f (g(y)) = y and g (f(y)) = x, then f and y are said to be inverse of each other. That means:

a) F = g
b) G = f
c) G = f^(-1)
d) F = g^(-1)



Answer
Correct Answer Is : G = f^(-1)
Solution Is :
In inverse trigonometric functions if y = f(x), then x = __________ .
