How would I determine the value of the trig ratios when I'm given the angle in radians for example #cot 0.942#? Trigonometry Right Triangles Trigonometric Functions of Any Angle 1 Answer bp May 13, 2015 Since #pi# equals 3.14, 0.942 would be #pi/10#. Therefore, if #cot (pi/10)# is given, all trignometrical ratios can be determined. #Sin (pi/10) = 1/sqrt(1+cot^2 (pi/10)# #cos (pi/10)= sqrt (1- sin^2 (pi/10)# #tan(pi/10)= 1/cot(pi/10)# #csc(pi/10)= sqrt(1+cot^2 (pi/10)# #sec(pi/10)= 1/cos (pi/10)# Answer link Related questions How do you find the trigonometric functions of any angle?
