For the triangle in Example 1, compute the tangent of both the non-right angles, and then use the inverse tangent function to find both angles. Check your work by finding the sum of those two angles. (What should it be?) In Example 3, find the length of side y. (First find the ratio to use, then solve it to find a formula for the unknown value ...

Use the following graphs to determine the limited domains on the tangent function used to insure the inverse is a function. Mark the axes that represent the angle measure. We use the names sin-1, cos -1 , and tan-1 or arcsin, arccos, and arctan to represent the inverse of these functions on the limited domains you explored above.

Name________________________________
inverse tangent (or. arctangent) of . x. denoted . tan-1x. or . arctan x. The domain of y = tan-1x is and the range is . It helps to think of the range of y = tan-1x as being along the right-hand side of the unit circle (minus the top and bottom points), which is traced out as angles range from (noninclusive).

The inverse tangent function is written as tan-1. Note that when you use the inverse trig functions on a calculator, The sin-1 function returns an angle in the interval. The cos-1 function returns an angle in the interval. The tan-1 function returns an angle in the interval. To find an angle for the secant, cosecant, and cotangent functions ...

When you use the inverse tangent key on your calculator it will always return either a positive (1st quadrant) or a negative (4th quadrant) angle. The inverse sine, inverse cosine, and inverse tangent values on a calculator are found by using the 2nd key. They are labeled and are found above the sin, cos, and tan keys.
