I have to calculate and plot the volume of a cicloid where a equals 27. Now, the assisstant gave us the supposed code to work with, as most were having trouble with it. Here it is:
However, this gives me the following error when trying to execute:
Error, (in plot3d) bad range arguments: ((27-27*cos(t))^2)^(1/2)*cos(s), ((27-27*cos(t))^2)^(1/2)*sin(s)
Now, only I and those I have sent this code verbatim to have experienced this error, while others in the class who typed it themselves didn't encounter this problem. I think there might be an assigned variable unaccounted for, but then again I did make sure to use restart. I am using Maple 16, for the record.
