In this lesson, learn what inverse trigonometric functions are, including inverse sine and inverse cosine functions. See examples to learn how to...
Graphing the Inverse Sine Function (1 of 2) One way to graph is to take points on the x is to take points on the graph of the restricted sine function and reverse the order of the coordinates. Graphing the Inverse Sine Function (2 of 2) Another way to obtain the graph of is to re...
These three graphs are all functions, BUT the second and third are ‘one-to-one’ functions, while the first is not. A line parallel to the x-axis will cross the graph twice, so it does not have separate y elements for every x value. An example of a ‘many-to-one’ function is ...
The curve drawn parametrically byx=f−1t,y=t, that is, the graph of the pointsf−1x,x, is the graph of the inverse of the inverse, and is therefore the graph off. This device will work to determine the principal branch of each of the trig ...
‘arccos’. it is used to measure the unknown angle when the length of two sides of the right triangle are known. the other inverse trig functions are also named in a similar way as per given in the below table. function inverse trig function sine arcsine cosine arccosine tangent arc...

Summary: The inverse trig functions (also called arcfunctions) are similar to any other inverse functions: they go from the function value back to the angle (or number). Their ranges are restricted, by definition, because an inverse function must not give multiple answers. Once you understand ...
Notation As you have just seen, the notation for these inverse trigonometric functions is unique. We use an exponent of -1 to let us know that we are dealing with the inverse trig function. We can write our inverse trig functions like this: Inverse Trig Functions ...

Recall that we can apply trig functions to any angle, including large and negative angles. But when we consider the inverse function we run into a problem, because there are an infinite number of angles that have the same sine. For example 45° and 360+45° would have the same sine. ...
