It starts at 0, heads up to 1 by π /2 radians (90°) and then heads down to −1. Cosine is just like Sine, but it starts at 1 and heads down until π radians (180°) and then heads up again. In fact Sine and Cosine …

Recall that the sine and cosine functions relate real number values to the x – and y -coordinates of a point on the unit circle. So what do they look like on a graph on a coordinate plane? Let’s start with …

In Section 7.2, we discussed how to interpret the sine and cosine of real numbers. To review, we identify a real number t with an oriented angle θ measuring t radians [1] and define sin (t) = sin (θ) and cos (t) …

When hand-drawing the graphs of sine and cosine, draw vertical dotted lines at intervals to remind you of the connection to the four quadrants from the unit circle and to keep your graphs accurate.
