Question

Exact values can be found for the sine of any angle.

Step-by-Step Solution

Answer

No, the Statement is false, Exact values can not be found for the sine of all angles, only a few angles have exact value and others do not.

Step 1. Given information

The given statement is 

Exact values can be found for the sine of any angle.

Step 2. Explanation

 Sine function has an exact value for only some specific angles like ${30}^{\circ },{90}^{\circ },{150}^{\circ },$etc.

but all other angles don't have an exact value, for that we need to use the calculator.

So  the statement that Exact values can be found for the sine of any angle is false.
