Here Radian measure of an angle=27π/4
we have to find the value of six trigonometric functions.
First i have converted radian measure of an angle into degrees.
27π/4=(27×180)÷4=1215°=3 Quadrants +135°=135°
which lies in second Quadrant.
As in second quadrant only sine, cosec ,function are positive.All other trigonometric function i.e cos,sec,tan,cot function will be of negative value.
