Calculate the curvature at the top of the curve of the parabola
Im sorry guys but Iīm getting nowhere. First of all. All I got is the formula but no examples in the literature except for the curvature of a circle. I need some examples. Second is curvature the correct word for this area of calculus. I read somewhere about concavity of a curve, is it the same thing?
I tried to put the second derivative of the function in the formula but it takes me nowhere.
Could somebody also explain to me why the curvature at the top of the curve must be ?
HELP!!
Please, I really need some help on this one. I canīt find anything useful anywhere on the internet or in my books.
What is the curvature at the top of the parabola
And how do I calculate it?
How do I know that slope=0 means the curvature is a?
Hereīs my effort, which probably is totally useless!
so we have:
uhhh....uuhhhh??? Is there a need for a calculation at all or do we only need to explain the obvious? (well not obvious to me, thats for sure!)
