No matter where P is on the circle ... Draw the horizontal line \(y = 0.75\). The line \(y = 0.75\) crosses the graph of \(y = \cos{x}\) four times in the interval \(-360^\circ \leq x \leq ...

Cosine and sine ... the property that the line from O to P makes and angle θ with the positve x-axis. cos(θ) is the x-coordinate of the point P and, sin(θ) is the y-coordinate of the point P. This ...

The graph of \(y = \cos{\theta}\) has a maximum value of 1 and a minimum value of -1. The graph has a period of 360°. Draw the horizontal line \(y = 0.5\). The line \(y = 0.5\) crosses the graph ...
