Use the alternative curvature formula K=|a x v|/|v|^3 to find the curvature of the following parameterized curves.
r(t)= (4+t^2,t)

Step-by-step explanation:

First of all, we calculate v and a as:

after that, we compute the cross product and we replace in the formula for k

a(t) X v(t) = (0,0,2)

| a(t) X v(t) | = 2

Hence we have
