I take pride in the neatness and accuracy of my tests and handouts. I am hoping someone can recommend a drawing program which will allow a me to draw most any required mathematical diagram with a minimum amount of input from the me. The program should provide specialized tools for drawing angles, graphs, normal distribution curves, Venn diagrams and right triangles and also comes supplied with a gallery of pre drawn diagrams.
Some of the above is a paraphrased description of a product I had purchased a couple of years ago called FX Draw. It is ok but still too many things I wanted to do were difficult or impossible to accomplish with this program. Sometimes I will use a program called SmartDraw. But still I wish there was one program which could do it all. What do you use for your math diagrams?
