# Maths Questions - Complex Numbers watch

1. I do not fully understand these questions mainly how to do the matlab parts. Some explanation and advise would be appreciated.

1. If z = −2 + 3j and w = 4 − 5j then using Matlab evaluate
a) modulus z, argument z, conjugate z, imaginary part of z and finally the real part of z.
b) Graph z and w on a suitable plot.
c) Evaluate z+w, z-w, z*w and z/w.
2. Using the Matlab file ’Solve Eqn’, change the computer code to solve
a) z
3 = 1
b) z
4 = 1
c) Provide a brief argument of what results you would expect for the equation z
8 = 1.
d) Solve by ’pen and paper’ the equation z
5 = 1 + j, and check your results with Matlab.
3. Just some help on how to start the questions is all i need. Its alright if you do not have matlab.

First you want to define your and before proceeding. Then part a can easily be googled for the commands.
