The horizontal shift is C. The easiest way to determine horizontal shift is to determine by how many units the starting point (0,0) of a standard sine curve, y = sin(x), has moved to the right or left. In the graph of 2.a the phase shift is equal 3 small divisions to the right. Transformations: Inverse of a Function . It is denoted by c so positive c means shift to left and negative c means shift to right. If c = 3 then the sine wave is shifted right by 3. 14. 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. Doing math equations is a great way to keep your mind sharp and improve your problem-solving skills. Since we can get the new period of the graph (how long it goes before repeating itself), by using \(\displaystyle \frac{2\pi }{b}\), and we know the phase shift, we can graph key points, and then draw . Vertical shift: Outside changes on the wave . It not only helped me find my math answers but it helped me understand them so I could know what I was doing. Tide tables report the times and depths of low and high tides. If c = 2 then the sine wave is shifted left by 2.
