I calculated the curvature, but I want to make sure I did it correctly.

- Consider the parametric curve f(t)= [ 4 (sin(3t))^2, 1-(cos(3t))^2, 2-2 (cos(3t))^2]. Calculate its curvature.
**What conclusion can you make about the curve based on this curvature?**

Hey kandygirl16.

What did you obtain for the result? Is it positive, negative or zero? What can you conclude given it's sign?

Do you know that curvature is

something like that, we use a different formula though
