[edit] Image:F(r,theta)=r sin(2 theta).png‎

Hello. Welcome here, and thank you for producing the graph at Image:F(r,theta)=r sin(2 theta).png‎. However, it appears to me that there might be a mistake. For instance, the picture seems to show that the function is not differentiable at the line x = 0, while it should be differentiable everywhere except at the origin. Could you please look into that? Additionally, it would be useful if you could add the commands you used and the program to produce the picture, so that we can reproduce the image if we want to change something.

Hello Jitse. Thank you for looking at the graph. I made a mistake, I uploaded a corrected version and added the script to the images page. Rubybrian (talk) 09:51, 11 December 2007 (UTC)
