Evaluate tan(pi)
tan(π)tan(π)
Step 1
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because tangent is negative in the second quadrant.
-tan(0)tan(0)
Step 2
The exact value of tan(0)tan(0) is 00.
-00
Step 3
Multiply -11 by 00.
00
