Phase Shift set a = 1, b = 1, d = 0 and change c starting from zero going slowly to positive large values. Take note of the shift, is it left or right, and compare it to − c / b. set a = 1, b = 1, d = 0 and change c starting from zero going slowly to negative smaller values. Both b and c in these graphs affect the phase shift in cosine graph (or displacement). The phase shift is the amount that the curve is moved in a horizontal direction from its normal position. If the phase shift is negative then the displacement will move to the left and if the phase shift is positive then the displacement will move to the right.

I am now trying to find the phase shift. I moved the 'working x-axis' 2 units down, in accordance with the vertical displacement of -2. Since the cosine function starts at 1 on the y-axis, how do I find the phase shift. If the x-axis is at -2, then the point where y=1 is a tiny fraction of a unit away from the y-axis. So how do I find the phase ...

Sliding a function left or right on a graph. By adding or subtracting a number from the angle (variable) in a sine equation, you can move the curve to the left or right of its usual position. A shift, or translation, of 90 degrees can change the sine curve to the cosine curve.
Phase Shift Changes To determine the phase shift, set the interior of the parenthesis equal to zero and then solve. The solution should either be positive or negative c/b. If the solution is positive, then shift the graph to the right by c/b. If the solution is negative, then shift the graph to the left by c/b

In both graphs, the shape of the graph begins repeating after 2π. Indeed, since any coterminal angles will have the same sine and cosine values, we could conclude that . sin(θ+2π) =sin(θ) and cos(θ+2π) =cos(θ) . In other words, if you were to shift either graph horizontally by 2π, the resulting shape
