This is called the center-radius form (or standard form) because it gives you both pieces of information at the same The simplest circle to graph has its center at the origin (0, 0). Because both h and v are zero, they can disappear and you can simplify the standard...

A standard cosine starts at the highest value, and this graph starts at the lowest value, so we need to incorporate a vertical reflection. Second, we see that the graph oscillates 3 above and below the center, while a basic cosine has an amplitude of 1, so this graph has been vertically stretched by 3, as in the last example.

The cons of circle graphs is that it's hard to compare two sets of data with each other. The numerical data that you display isn't very exact. You should usually only use a circle graph if you have between 3-7 categories that you're comparing. Lastly, circle graphs can only be used with discrete data. Line graphs

Let's take a look at this graph by making a table of (x, y) coordinates, but we'll match them up with the t's and keep track of those, too. The x-coordinates of each point on the graph of this function are given by x = f(t), and the y's by y = g(t). The (x, y) pairs are plotted in the graph below. When a valid equation/inequality is entered into a command line, Desmos will — by default — plot its graph by assuming the full domain under which the equation/inequality is satisfied. However, this doesn’t always yield the desired effects, and there are occasions where it’s preferable not to do so.
