Find the Exact Value tan(1 degree )

Problem

tan(1)

Solution

1. Identify the expression as the tangent of one degree.

2. Recognize that 1 is not a standard reference angle (like 30 45 or 60.

3. Express the value using the relationship between degrees and radians, where 1=π/180 radians.

4. Determine if a simpler radical form exists. While tan(1) can be expressed using complex nested radicals via the half-angle and angle-subtraction formulas (e.g., 1=3−2, such expressions are extremely lengthy and typically not considered "simpler" than the trigonometric notation itself.

5. Conclude that the exact value is most concisely represented as tan(1) or tan(π/180)

Final Answer

tan(1)=tan(1)
