How do you find the value of #csc (sin (2/3))#? Trigonometry Right Triangles Trigonometric Functions of Any Angle 1 Answer Nghi N. Jun 11, 2015 Find the value of csc (arcsin (2/3)) Explanation: #sin x = 2/3# --> x ? #sin x = 2/3 = 0.67 # --> #x = 41.81# and x = 180 - 41.81 =# 138.19# a. #csc (41.81) = 1/sin (41.81) # = #1/0.67 = 1.49# (Quadrant I) b. #csc (138.19) = csc (-41.81) = 1/sin (-41.81)# = #= 1/-0.67# = -1.49 (Quadrant II) Answer link Related questions How do you find the trigonometric functions of any angle?
