If you want to improve your performance, you need to focus on your theoretical skills. Now consider the graph of y = sin (x + c) for different values of c. g y = sin x. g y = sin (x + p). Both b and c in these graphs affect the phase shift (or displacement), given by: `text(Phase shift)=(-c)/b` The phase shift is the amount that the curve is moved in a horizontal direction from its normal position. \hline 5 & 2 \\ A horizontal shift is a movement of a graph along the x-axis. Later you will learn how to solve this algebraically, but for now use the power of the intersect button on your calculator to intersect the function with the line $y=8$. As a busy student, I appreciate the convenience and effectiveness of Instant Expert Tutoring. This horizontal movement allows for different starting points since a sine wave does not have a beginning or an end. To solve a math equation, you need to figure out what the equation is asking for and then use the appropriate operations to solve it. A periodic function that does not start at the sinusoidal axis or at a maximum or a minimum has been shifted horizontally. Steps to Determine Amplitude, Period, & Phase Shift of a Sine Function From its Graph. A shift, or translation, of 90 degrees can change the sine curve to the cosine curve. It all depends on where you choose start and whether you see a positive or negative sine or cosine graph. 14. Given the following graph, identify equivalent sine and cosine algebraic models.
