Trigonometry – Graphing CSC and SEC

Former US President Barack Obama trades in the nuclear codes for a whiteboard and some markers. He's now Mr. ObaMATH, and he waxes poetic on graphing trigonometric functions, in this case, cosecant (CSC) and secant (SEC). These two functions are reciprocals of SIN and COS, so we use their graphs as guides, graphed over one period. They also involve asymptotes. Welcome to the Oval Office, and thank you for joining the learning – YAY MATH!
