Write the equation of a line in polar form

The video tutorial explains how to convert a rectangular equation into a polar equation. It begins by introducing the concept of polar equations and the need to replace X and Y with R and Theta. The instructor emphasizes that these conversions are not found on formula sheets and must be understood conceptually. The process involves replacing X with R cosine Theta and Y with R sine Theta. The tutorial then demonstrates how to solve for R by factoring it out and rearranging the equation. The final result is presented as R equals 7 divided by 3 cosine Theta plus sine Theta.
