I was looking for some kind of a plotter, graphic calculator to produce images, such as eclipse, parabola, logarithm etc. I saw one on wikipedia https://en.wikipedia.org/wiki/File:Lemniscate_of_Booth.png which is designed using a software called Mathpad, but it is not available for Linux. Is there something equivalent for the Linux world?
I have tried
bc for simple calculations. I do not want python because it's a very generic script with a huge footprint ( packages ). I have used R for statistics. I don't know any other software in the Linux world.
Something, small, neat and just does the mathematics is enough for me and I think MathPad ( even if I have not tried myself ) looks at the first glance quite ok to me.
