Graphs of the Sine and Cosine Functions - Kean University

using quotients and reciprocals of the sine and cosine functions. They are as follows. tangent: tanx sinx cosx cotangent:cotx cosx sinx secant: secx cos1 x cosecant: cscx 1 sinx Since these functions involve reciprocals, they are undefined whenever the denominator is zero. Example 3 Sketch a graph of tanx from x 0tox . Solution ................
