+4 Two students are calculating the exact value of tan(7pi/12)? Choose one of the following to methods to solve.
-Student A says 7pi/12 is half of 7pi/6, and they will use the half-angle identity and the unit of circle to solve.
-Student B says 7pi/12 is equivalent to pi/3+pi/4, and they will use the sum formula and the unit of circle to solve.
