- So we see them here as a solution to fourth order equations with point loads are cubic splines. Because the big key point is that there's a jump here in u triple prime, the third derivative. A jump in the third derivative, that's what we saw here.
- I am trying to solve a fourth order Differential Equation (no previous Diff Q experience) and I'm running into issues with the ode45 function. I think I have entered the differential equations correctly in order for MATLAB to see them as first order equations. Any help is welcome. The equation would

- Shortly after the discovery of a method to solve the cubic equation, Lodovico Ferrari (1522-1565), a student of Cardano, found a way to solve the quartic equation. His solution is a testimony to both the power and the limitations of elementary algebra.
