Find the Exact Value tan(12/5)

Problem

tan(12/5)

Solution

1. Identify the expression as the tangent of a constant value given in radians.

2. Determine if the value 12/5 corresponds to a standard angle on the unit circle. Since 12/5=2.4 radians, it is not a multiple of π or a common reference angle like π/6 π/4 or π/3

3. Conclude that because the input is not a standard angle, the exact value is expressed simply as the function applied to the argument.

Final Answer

tan(12/5)=tan(12/5)
