Q1. Write a MATLAB (C, C ++, or Java) implementation that applies the Secant's method to find a root of the equation eA sin- B - 0.432506 by taking the termination criteria 10-1e Q2. Write a MATLAB (C, C +, or Java) implementation that applies the modified Gauss elimination method to solve the particular system u14 + u15 = 2.4756 Q3. Write a MATLAB (C, C ++, or Java) implementation that takes the number of data points n (which is not less than 5) as input; creates arrays for and y values of the data points and asks user to enter these values; constructs the best polynomial P> (x) - ac d and gives it as the output Q4. Obtain a third order of accuracy approximation formula for y" (0). You can make use of MATLAB software Q5. Consider the second order differential equation with Neumann boundary conditions 0
