USING C++, write a simple class defining complex numbers USING the FRIEND function (READ BELOW) Write a C++ defining a class for complex numbers. A complex number is a number of the form: a + b ∗ i , where, for our purposes, a and b are numbers of type double, and i is a number that represents the quantity √−1. You should represent a complex number here as two values of type double. You should name the variables real...

PART 1 Modify the class ArrayList given in Exercise 1 by using expandable arrays. That is, if the list is full when an item is being added to this list, the elements will be moved to a larger array. The new array should have twice the size of the original array. Using the new class ArrayList, write a program to store 1,000 random numbers, each in the interval [0, 500]. The initial size of the array in the class should...

write MATLAB scripts to solve differential equations.
Computing 1: ELE1053 Project 3E:Solving Differential Equations Project Principle Objective: Write MATLAB scripts to solve differential equations. Implementation: MatLab is an ideal environment for solving differential equations. Differential equations are a vital tool used by engineers to model, study and make predictions about the behavior of complex systems. It not only allows you to solve complex equations and systems of equations it also allows you to easily present the solutions in graphical form....
