The curvature of the function f(x) = x^3 – x + 1 at x = 1 is given by?
(a) ∣^6⁄5∣
(b) ∣^3⁄5∣
(c) \(\left |\frac{6}{5^{\frac{3}{2}}} \right |\)
(d) \(\left |\frac{3}{5^{\frac{3}{2}}} \right |\)
The question was posed to me in homework.
This key question is from Curvature in portion Differential Calculus of Engineering Mathematics
