- Engineering problem of Statics
Here is a cantilever affected by non-uniform distributed load (N/m). The cantilever is on statically equilibrium state currently. 5 points of non-uniform distributed load are given. (Neglect the load affected by the weight of cantilever itself.)

3. Discuss and Result
- compare methods
There are several method to make polynominal. But we don't know about the function and only have the 5 points, we can use just 3 method to solve this problem.
① Lagrangian Polynominal
② Method of undetermined coefficents
③ Iterated Interpolation + ④ Matlab's Polyfit function
If we have n+1 datas, there exists a unique polynominal P of degree at most n.
So if we solve the problem with any method, the polynominal must be same.(or similar because there exists some errors.) To prove it, I solve this equation by Lagrangian Polynominal and Method of undetermined coefficients and compare with other ones.
