How do you find all six trigonometric function of #theta# if the point #(sqrt2,sqrt2)# is on the terminal side of #theta#? Trigonometry Right Triangles Relating Trigonometric Functions 1 Answer Kalyanam S. Jun 20, 2018 As below. Explanation: #(x,y) = (sqrt2, sqrt2)# #tan theta = y/x = sqrt 2 / sqrt2 = 1, theta = pi/4# #cot theta = cot (pi/4) = 1 / tan (pi/4) = 1# #sin theta = sin (pi/4)= 1 / sqrt2# #cos theta = cos (pi/4) = 1/sqrt2# #csc (theta) = 1 / sin theta = 1/ sin(pi/4) = sqrt2 # #sec (theta) = 1/cos theta = 1 / cos (pi/4) = sqrt2 # Answer link Related questions What does it mean to find the sign of a trigonometric function and how do you find it?
