For example, i have the field x*e_x+y*e_y. Is there a command for transforming it into the same field with polar coordinates and polar unit vectors?

Hi

So the question is to find complex number W from :

.

but I want the answer in polar form using e (Euler's number).

The question is specific to ask for the complex number W that lying in the first quadrant and having the largest possible real part. I calculated and got :

There no curve on the second of the following two polar plots. Why? (I am using the 64 bit version on W7)

restart:

with(plots):

polarplot([3+4*cos(theta)],theta=0..2*Pi, radialstart=-2,angularorigin=bottom,legend=["Zero wind"], legendstyle=[location=top,font=[Times,roman,14]],labels=["G-force [G]",""], font=[Times,roman,14],labelfont=[Times,roman,14],

Hi guys

i have a problem to drawing this function

problem is F(r,theta)=sin(6r) /6r   IF r is not 0

          and F(r,theta)=1               IF r is 0

Thanks for your helps 

I've been trying to find a way to plot error bars in a polar coordinate system. Using ErrorPlot i can display my data with error bars in cartesian coordinates but the usual option 'coords=polar' doesn't seem to be followed. Perversely, the option 'axiscoordinates=polar' does work in ErrorPlot, so i just get a cartesian plot of my data sitting on top of a polar axis. Is there a way to plot my data with errors in a polar basis?
