does anyone know an easy to use 3d plotting software with vectors? i have been using maple for some things but 3d plotting vectors and transformations is really slow in maple. i really like geogebra but it can only do 2d vectors. any suggestions?

Hi, I have been trying to integrate an equation and then plot the result using MATLAB but haven't figured out how to do it. Say, I have an equation of the form dy = (1/x)dx. I want to integrate the above equation and then plot y as a function of x. So, to integrate I do this: syms y x...

hi, i need to know how to plot the change of variables am i just to take x, and y as different constants, and treat it as normally on the (u,v) axis? so for the first, it will be like plotting on the (x,y) axis something like y^2 = x^2 - c, for different c, how many lines would i need to plot...
