This is a parabola.
Let y=t, then
I'm having a little trouble finding the radius of curvature for problems of the following form
For examples. I'm asked to find the radius of curvature at the point (0,0) for the curve
it's at this point where I'm sure I've messed up. If anyone could tell me how to solve these types of questions I'd be very grateful
Ah, so I did a little reading this morning, and I can now work through it parametrically. However this question was in the exercise right after the cartesian method had been explained, the parametric method hadn't even been covered yet. The logical conclusion is that you can solve this using cartesian method. But I'm not sure how since I keep getting situations where I'm dividing by zero!
