Question #eadac

Answer 1

See below

Explanation:

If you are in mode "degrees", then just push the "sin" button followed by the number "75" in brackets.

If you are in mode "radian", then you have to convert the 75° in radians first:

`(180°)/(pi) = (75°)/?`

`? = 1.30` radians

This means that 75° is 1.30 radians.

Now, put your calculator in mode "radian", then just push the "sin" button followed by the number "1.30" in brackets.

Regardless of the method you use, you should get the same result, which is a way to verify if your calculation was done properly.
