use a calculator to find the values of the inverse function in radians. sin -1 (0.65) tan -1 (-0.09)

You need to key in the numbers and press the correct keys. What is the difficulty?

There is no equation for this. This is what you do: 1. Set the calculator to radian mode. 2. Enter the number 0.65 3. Press the inverse sine function. You may have to press a "second function" key first, followed by a sine key, but this depends on how your calculator works. Then follow the same procedure for the inverse tangent of -0.99
