Fill in the values of the trigonometric functions chart with

Fill in the values of the trigonometric functions chart with the angle

Solution

                    Using the values of common trigonometric values we can fillupt the table

Further sinx = 1/cscx ; cosx = 1/secx ; tanx = 1/cotx

                    sin ----cos-----tan-----cot-----sec-----csc

angle =0 deg: 0--------1 --------0 ------- undef----1 -------undef

angle 90 deg : 1 ------0 ------undef ---------0 ------undef-----1

angle 180 deg : 0 ----- (-1)-----0------undef---------(-1)---- iundef

angle 270 deg: -1 -----0 -------undef----0 ------undef------ (-1)
