t = linspace(1,5,100) Finding the cubic spline using the function: splineX = spline(x,y,t); I have used the command to be able to plot function splineXbut I'm not sure how I can find the actual equation the spline function calculates (I know that for this data it would simply be a straight line but... The corresponding formulae for solving cubic and quartic equations are signiﬂcantly more complicated, (and for polynomials of degree 5 or more, there is no general formula at all)!! In the next section, we shall consider the formulae for solving cubic equations.

Chapter 03.02 . Solution of Cubic Equations . After reading this chapter, you should be able to: 1. find the exact solution of a general cubic equation. how to get bank logins This is a cubic equation in h 2, with known coefficients, since we know e, f, and g. We can use the solution for cubic equations shown above to find a positive real value of h 2 , whose existence is guaranteed by Descartes' Rule of Signs, and then take its positive square root.
