Simplify cos(10)

Problem

cos(10)

Solution

1. Identify the expression as the cosine of the number 10.

2. Determine the units of the argument. Since no degree symbol is present, the argument 10 is assumed to be in radians.

3. Evaluate the expression. The value cos(10) does not correspond to a standard reference angle in trigonometry and cannot be simplified into a more basic exact form using radicals or integers.

4. Conclude that the expression is already in its simplest exact form.

Final Answer

cos(10)=cos(10)
