Mr. Rose for #39 you divided by the wrong dx/dt when calculating d^2y/dx^2. It would be concave up on the interval (0, inf).
Oops. Yup, you're right.
Have you make a lecture on the basics of parametrization?if yes then please share the link because I find but I didn't get it.
This doesn't start all the way at the beginning, but almost: th-cam.com/video/0nF5SWA1Q8w/w-d-xo.html
