### College Board - LaTeX?

Piecewise function produced by the College Board

Does anyone know what program the College Board uses to plot, draw figures, etc.? A screenshot of one of their plots is attached. I can't really tell if they use LaTeX.

Welcome to the forum!

It doesn't look perfect, so it's either not done with LaTeX or it's not done very well. For example, the function plot at the left is not smooth, and the base line of the origin doesn't match the base line of the numbers at the x tick marks.

The question is: would you like to imitate the College Board, or would you like to recommend us a very good way of plotting and drawing? My strong recommendation would be pgfplots for plotting and TikZ for general drawings.

Their figures may not be perfect, but they do construct other interesting figures with the same program. Take a look at the arrows that point to the electrodes in the galvanic cell below. The arrowheads are exactly the same as the ones used for the axes in the original post. Could they just be using a program like Photoshop or Illustrator? Also, how can I label the origin as O in LaTeX? Can I make it so that there are only 2 ticks on the y-axis like they did? Thanks.

Sure, but I assume they use LaTeX. But there are possibilities, such as picture environment, PSTricks, or TikZ. Triangle arrow heads are not so special.

Put an \$O\$ there, as a node or text.

Sure, it depends on how you are doing it. Just put not more than 2 then.

Of course, but I guess they use LaTeX. But looking at picture environment there is possibilities of using PSTricks, or TikZ.
