Ok, so Ive been given a curve in polar coordinates. I came up with a parameterisation: x(t)=rcos(theta) y(t)=rsin(theta) But now I have to plot the graph using matlab and I have no idea. Theta lies between 0 and 2pi. This is what I put in and got back in matlab: >> t=[0:pi/50:2pi] ??? t=[0:pi/50:2pi] | Error: Missing MATLAB operator. Cheers.
