Question

How do you use a calculator to evaluate `sin10^circ`?

Answer 1

`sin 10 = 0.1736`

Explanation:

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.
