hi everybody

so far i plotted functions where z values were functions z=f(x,y) in cartesian coordinates. this was easily done with the plot3d command. now i have a function described in polar coordinates, z=f(r,phi). so far i haven't succeded in plotting it. as far as i see it cylindrical coordinates would be required here, but maple expects r=f(z,angle) and i need z=f(r,angle). maybe a changecoords operation would help, but I'm not sure how to perfrom that (I've just started using maple). would be thankful for pointers on how to tackle my problem.

hi all,

i am quite an unexperience user so the solution to my problem might be obvious to you... i googled for a while and couldn't find anything regarding this matter.  i just want all my plots with maple to use the exponential notation on the y-axis. from what i've observed maple does that when values are on the E-6 regime or smaller, greater numbers are just written out which looks just ridiculous (e.g. .0005 -  i want 5x10^E-4). so is there a way to fix this, set some parameter that would force maple to use the exponential notation from earlier on?
