Hope this helps.

The six trigonometric functions are

#sin, csc, cos, sec, tan, cot#

#pi " is in second quadrant. Hence, only " sin, csc " are positive as per the chart above"#

#sin t = sin pi = sin 0 = 0#

#csc pi = 1/ sin pi = 1 / 0 = oo#

#cos t = cos pi = -1#

#sec pi = 1 / cos pi = 1 / -1 = -1#

#tan t = tan pi = -0/ -1 = 0#

#cot pi = 1/ tan pi = -1 / 0 = -oo#
