Inverse
Functions
The graphs of the
inverse trigonometric functions can be obtained by reflecting the graph of the
function about y = x.
Graph of y =
sin-1 x
Properties of the
Inverse Sine Curve
1. The graph is
symmetrical about the origin.
2. The graph only
defined for the principal values of the sine function.
Graph of y =
cos-1 x
Properties of the
Inverse Cosine Curve
1. The graph is
symmetrical about the point (0, p/2).
2. The graph is
only defined for the principal values of the cosine function.
Graph of y =
tan-1 x
Properties of
Cotangent Curve
1. The graph is
symmetrical about the origin.
2. The graph is
defined for the entire range of x.
3. There are 2
horizontal asymptotes, at y = p/2
and y = -p/2.
