Use a calculator to find the approximate value of sin-1( 0.635).
To find the approximate value of sin^(-1)(0.635) using a calculator, follow these steps:
1. Turn on your calculator and make sure it is set to the appropriate mode (either degrees or radians).
2. Locate the sin^(-1) or arcsin function on your calculator. It is often denoted as "sin^(-1)", "arcsin", or "sin⁻¹". On most calculators, you can find it by pressing the "2nd" or "SHIFT" key, followed by the key with "sin" or "sin⁻¹" labeled on it.
3. Once you have located the sin^(-1) function, enter the value 0.635.
4. Press the "=" or "Enter" button on your calculator to get the result.
The calculator will display the approximate value of sin^(-1)(0.635), which represents the angle whose sine is approximately 0.635. Keep in mind that this result will be in either degrees or radians, depending on your calculator's mode setting.
