What are the six trig function values of -405? Trigonometry Right Triangles Trigonometric Functions of Any Angle 1 Answer Nghi N. Nov 2, 2015 Find the trig function ratio of (-405) Explanation: sin (-405) = sin (-45 - 360) = sin (-45) = - sin 45 = - sqrt2/2 cos (-405) = cos (-45 - 360) = cos (-45) = cos 45 = sqrt2/2 tan (-405) = sin/(cos) = -1 cot (-405) = -1 sec (-405) = 1/(cos) = 2/sqrt2 = (2sqrt2)/2 = sqrt2 csc (-405) = 1/(sin) = -2/sqrt2 = - (2sqrt2)/2 = - sqrt2 Answer link Related questions How do you find the trigonometric functions of any angle?
