Derive the basis functions Ni,3(u) and find the equation for the open quadratic B-spline curve defined by five control points p0, p1, p2, p3, and p4.
I know the formula is P(u)= the sum of n,i=0(PiNi,k (u))
it's difficult to type the formula in this text box. I hope you can understand it.

I am afraid I do not understand the formula. Sorry
