Derive the numerical method formula and help me write
an Octave code using Euler's method (ode45).
The following equation can be used to model the deflection of a sailboat mast subject to a wind force: d²y = (L z)² - dz² 2EI where f= wind force, E = modulus of elasticity, L = mast length, and I = moment of inertia. Calculate the deflection if y = 0 and dy/dz = 0 at z = 0. Use parameter values off= 60, L=30, E = 1.25×108, and I = 0.05 for your computation.
