$sin 10 = 0.1736$

First check the settings on your calculator.
There are three ways to give angles : degrees, radians and grads.

We usually use degrees for trig.

Depending on your calculator, you will press keys as:

$"sin" 10 = " "$ and the display will be 0.1736...#

Or you will key in:

$10 sin" "$ and the display will be 0.1736... immediately.
