Document Summary

Mat135h1 f - calculus 8th edition (stewart) - appendix d. Can use it as a conversion factor between degrees and radians. Arcs: l r or l = r where r = radius, = angle subtended by arc, l = length of arc. Note that these equations are only valid when is in radians. 1 radian is when l is equal to r. Standard position of an angle is when vertex is at origin of coordinate system (x/y plot) and initial side lies on positive x-axis. Positive angle: initial side rotated counterclockwise to reach terminal side. Negative angle: initial side rotated clockwise to reach terminal side. Origin (and vertex) - intersection of x-axis and y-axis. Trigonometric functions csc = sec = cot = O r y r x x y sin = cos = tan = A y r x r y x y = 0 x = r initial side = terminal side; angle = 0.
