Find the Exact Value cos(1)

Problem

cos(1)

Solution

1. Identify the expression as the cosine of 1 radian.

2. Determine if the value can be simplified into a more basic algebraic form or a fraction involving square roots.

3. Conclude that since 1 radian is not one of the standard angles (like 0 π/6 π/4 π/3 or π/2, its exact value cannot be expressed in a simpler algebraic form.

4. State the exact value as the expression itself.

Final Answer

cos(1)=cos(1)
