Square Roots of Complex Numbers

In class, we learned how to find the square roots of complex numbers.  We also learned how to take the cube and fourth roots of complex numbers by solving some sample problems.  

Complex Number Arithmetic

Today in class, we learned about complex number arithmetic. We learned a new notation involving cis instead of (cos + i sin). Also, we learned how to multiply and divide complex numbers. Finally, we learned Moivre's Theorem when dealing with powers and complex numbers.
