The inverse of only one to one function exists? Sine function is one to one? If a function is not one to one, it may be made so by restricting its domain? A sine function is said to be principal sine function if its domain is restricted to the interval [-π/2, π/2] The inverse sine function can also be written as arc sin x?

The domain of principal tangent function is [0, π] ?The graph of y= tan –1x is obtained by reflecting the restricted portion of the graph of y= tan x about the line y =x? The horizental line between y=1 and y = -1 intersects the graph of y = sin x ________?times? For the graph of y = sin –1 x, the restricted portion of the graph of y = sin x is reflected about ______?
