Summary
Well, we've come a long way in a few pages. We've now seen how complex numbers can be expressed in the three forms of Cartesian, polar, and exponential. We've also seen which forms are better for different operations. You've learned how to multiply, divide, add, and subtract complex numbers. Finally, we've put it all together to mathematically derive the Bloch sphere. Bravo!
In the next chapter, we will explore the world of eigenvalues, eigenvectors, and all kinds of eigenstuff. Get ready!
