use the three methods in the pic

Image text transcribed for accessibility: Use the following methods to solve for the maximum deflection (minimum y value) in the beam. Take the derivative by hand and use the fzero function to find the minimum. Use the gradient function to numerically calculate the derivatives and find the minimum within 1 mm Use fminsearch to find the minimum value for the deflected beam. Display all your results. Figure P5.13a shows a uniform beam subject to a linearly increasing distributed load. The equation for the resulting elastic curve is (see Fig. P5.13b) y = w0 / 120EIL (- x5 + 2L2x3 - L4x) (P5.13) L = 600 cm, E = 50.000 kN/cm2, I = 30,000 cm4, and w0 = 2.5 kN/cm.
