Question

Anybody good with parametric curves

Answer 1

I have a question: On my homework, it says that I have to compute the left most point of the parametric. I do know that in order to find the left most point, you have to set dx/dt equal to zero and find t. However, how do I know for sure that it is the left most and not the right most?

Answer 2

if you set \(\frac{dy}{dx}=0\) you find the value of \(t\) here the curve has a horizontal tangent, not the left or right endpoint

Answer 3

finding the left or right endpoint is probably a matter of thinking about the domain of \(x\) in terms of \(t\)
for example, if \(x=t^2+1\) then the least \(x\) can be is \(1\)
