How do you find the exact values of cot, csc and sec for 30 degrees? Trigonometry Right Triangles Trigonometric Functions of Any Angle 1 Answer Chandra S. Oct 3, 2015 sin#30^0# = 1/2, cos #30^0# = (#sqrt# 3) /2 and tan #30^0# = 1 / #sqrt# 3 Now csc #30^0#= 2,sec #30^0# = 2/#sqrt# 3 and cot #30^0# = #sqrt#3 Answer link Related questions How do you find the trigonometric functions of any angle?
