Please help with this Matlab question!!

6) Using MATLAB create 5 Hz square wave with an amplitude of 2 V for at least 3 cycles, by adding 3 sine waves. Adjust each of the 3 sine waves frequencies and amplitudes in order to create the best approximation of the square wave. This process can be a trial and error process, or you can use a formula that simplifies the process. Repeat this approximation using 5 sine waves, and 7 sine waves. Provide all your code, three square wave plots (Ising 3, 5, 7 sine waves), and the formula used. Discuss the results. 6) Using MATLAB create 5 Hz square wave with an amplitude of 2 V for at least 3 cycles, by adding 3 sine waves.
