Little confused on this? Just working on parametric equations, I have x= sin theta/2 & y = cos theta/2... and I have to create a plot table between -pie and pie. I don't know if Im supposed to use the radians as the parameter for the plot table or just degrees? i'm confused...

HI!!

always use radians, they are numbers

if it is
\[x=\sin(\frac{\theta}{2}), y=\cos(\frac{\theta}{2})\] you should get a circle
