The video tutorial explains how to convert equations from rectangular to polar form and vice versa. It begins by introducing the concept of polar equations and the conversion of X and Y using cosine and sine functions. The tutorial then demonstrates solving polar equations by substitution and factoring to isolate R. Finally, it covers converting polar equations back to rectangular form, which can be used in calculators.
