In MATLAB:

- Solve the second order differential equation y(x)+py(x)+qy(x)=0 for different values of p and q parameters. What is the influence of the sign of the characteristic equation discriminant (D=p24q) to the solution? Visualize the obtained results. - Solve the set of equations {dtdx1=x2dtdx2=x1kx2. Visualize and interpret the results for different initial conditions and values of the parameter k (large: k>2 and small 0
