An easy way to find the vertical shift is to find the average of the maximum and the minimum. For cosine that is zero, but for your graph it is $\frac {-1+3}2=1$.

Feb 17, 2019 · Does anyone here have a good explanation of what a phase shift is, and perhaps also how (given solid knowledge of the definition) I could go about solving the graph problem …

Feb 3, 2022 · You might interpret your phase shifts as follows. For the left-moving wave, +, $\phi_+$ is the amount you need to shift the true origin of the cycle, x =2, to the left, to position …

Dec 2, 2014 · 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.

Sep 25, 2024 · The amplitude of the graph is found by taking half of the difference between the maximum value and the minimum value. $$|A| = \frac {\text {maximum value} - \text {minimum …

Apr 7, 2018 · On phase shift, that's generally how I think about any old translation on the graph (i.e. y= (x-2) is the line y=x, but it starts two units to the right). But especially with sinusoidal …

Aug 31, 2023 · I had it in my mind that phase shift meant how much the graph will shift horizontally with respect to first graph. But upon graphing $y = \sin (x)$ and $y = -\sin (x)$, I …

May 1, 2016 · I am confused why d is not in this equation as the graph has been vertically shifted -1 units or is it that c is -1 in this graph? For B or the period, a period of 1 is $360^ {\circ}$ but …

Aug 24, 2015 · How can i calculate the Fourier transform of a delayed cosine? I haven't found anywhere how to do that. This is my attempt in hoping for a way to find it without using the …

Oct 1, 2014 · Now, if we do this with every one-to-one component function, we find that all of these components are stretched (or compressed) and shifted horizontally in the same way, …
