I have a problem where I had to graph a complex number in the complex plane. The problem is: Given the complex number -4 + 5i, graph the complex number in the complex plane. I did this and got 0 to -5.
The second part of the problem is calculate the modulus. When necessary, round to the tenths place. This I do not know how to do. Can someone please explain how I should go about this? Thanks for your help.
