The graph of the Secant function. The secant function is defined by assigning to the angle ( the reciprocal of the x-coordinate of the ordered pair where the terminal side of the angle ( crosses the unit circle (e.g. ). 1. Using the definition of secant, fill in the following chart with the output for the secant …

Mark the point on segment CD where the secant intersects the circle, and label it E. Mark the point on segment BD where the secant intersects the circle, and label it F. While holding down the shift key, highlight points A, F, and E, in that order. Go to Construct, Arc on circle. Go to Display, Show label. Go to Measure, Arc angle.

secant of : sec = r/x. cosecant of : csc = r/y. These four trig functions can be written in terms of sin and cos of The last one shows that the cotangent and tangent are reciprocal functions. Secant and cosine, as well as Cosecant and sine are reciprocal funtions. It is easy to memorize the signs of the six trig functions.
