Graphs of Cosine and Sine. Cosine and sine of an angle θ are defined to be the x and y-coordinates of the point P on the unit circle with the property that the line from O to P makes and angle θ with ...

The graph of \(y = \sin{\theta}\) has a maximum value of 1 and a minimum value of -1. The graph has a period of 360°. This means that it repeats itself every 360°.

Plot tan, cot, sec and csc on the interval [-2Pi, 2Pi]. (Note that these functions all have vertical asymptotes.) You should know these graphs well. The trigonometeric functions are all periodic, that ...
