The video tutorial by Mr. Tarrou covers the representation of complex numbers in both rectangular and polar forms. It begins with an introduction to complex numbers and their representation in a rectangular coordinate system. The tutorial then explains how to calculate the absolute value of complex numbers using the Pythagorean Theorem. Following this, the video demonstrates the conversion of complex numbers from rectangular to polar form, including the calculation of the angle theta. Finally, it covers the process of converting complex numbers back from polar to rectangular form, emphasizing the importance of using the correct mode on calculators.
