Question

The Eqaution of cubic curve is y=x^3+x^2-x+1
find the gradient?

Answer 1

gradient = derivative of y

Answer 2

ok and to derive y?

Answer 3

differentiation of x^n is n. x^{n-1}
use this to differentiate 1st three terms.
also, differentiation of constant =0.
so, work out differentiation of y (dy/dx) and tell us what you get.
