Find the exact values of the six trigonometric functions for angle theta in standard position if a point with the coordinates (-6, 6) lies on its terminal side.Note: A value such as sqrt3/2 can be entered as sr3/2.

Answer:See below Step-by-step explanation:We can use the unit circle to figure out the trigonometric functions of the angle θ.
The x- and y-coordinates are in the second quadrant, so θ is an obtuse angle (135°), as seen in the figure below.
sinθ = 6/(6√2) = 1/√2 = √2/2
cosθ = -6/(6√2) = -1/√2 = -√2/2
tanθ = 6/(-6) = -1
cotθ = -6/6 = -1
secθ = (6√2)/(-6) = √2
cscθ = (6√2)/6 = -√2
