👉 Learn how to graph a cosine function. To graph a cosine function, we first determine the amplitude (the maximum point on ...

Learn the basics to graphing sine and cosine functions. The sine graph is a sinusoidal graph with x-intercepts at x = 2n*pi, maximum value of 1 at x = pi/2 + 2n*pi, and minimum value of -1 at x = ...

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 positve x-axis. cos(θ) ...

What do you think the graph of \(y = \cos 2x^\circ\) would look like? amplitude = 1, so the distance between the maximum and minimum values is 2 number of waves = 2 (period is 360˚ ÷ 2 = 180˚) graph ...

In a function such as sine or cosine, we could also have a translation of the form: \(y = \sin (x - a)^\circ\) where \(a\) is called the phase angle. This is when the graph of the function has been ...
