(computer algebra) using mathematica, maple, or some other computer algebra package, apply the poincaré-lindstedt method to the problem č + x - x = 0, with x(0) = a, and (0)=0. find the frequency w of periodic solutions, up to and including the o(& *) term.

Your program should prompt the user for the dimensions of the two squares matrices, making sure that the user input is greater than or equal to 4.[ yes, an example would be a4x4matrix]2.if the above is not met, prompt the user for a new value.3.now generate random integernumbers to fill both matrices.4.display these two matrices on the screen.5.multiply the two matrices and display the result on the scre
