I demonstrate how to calculate the modulus of z1 and z2, finding that it equals 3 root 2, and I calculate the argument to be pi over 4. I also show how to express complex numbers in polar form and solve inequalities related to them. I encourage viewers to follow along with the calculations and practice similar problems to strengthen their understanding. Please make sure to review the steps carefully as they are crucial for mastering these concepts.
