I have been for long looking for some software apps which can help me draw various mathematical and geometrical figures and drawings.Can someone please tell me something about these which will run on Windows or Android ?
It is a vector graphic program that works for Mac/Linux/Windows. It is not strictly mathematical, but is intuitive and produces pictures with high enough quality.
If you wish, a bit more complex drawings are possible too (the cone below was drawn by hand in 2D).
I hope it helps $\ddot\smile$
