what should a and b look like discribed here?

Find the arctangent of zero and infinity in both degrees and radians.
a. First, express both the degree and the radian solutions numerically using the evaluation function (equal sign)
b. Then express the radian values as EXACT solutions using symbolic evaluation. (right arrow)
