PPT-8.2.4 – Rewriting Polar Equations

We talked extensively about converting rectangular to polar equations Use the substitutions x rcos ϴ y rsin ϴ x 2 y 2 r 2 t an ϴ yx Now we will take something in terms or r and . Equations of the form dy dx are called Riccati equa tions If is kno wn particular solution to Ricatti equation then the substitution will transform the Riccati equation in to Bernoulli equation a If then what do and equal in terms of and Solution If ab be a continuous function and 0 then the area of the region between the graph of and the xaxis is de64257ned to be Area dx Instead of the xaxis we can take a graph of another continuous function such that for all ab and de64257ne the area o thermal$ stable Both the Southern the Southern almost exclusively ice). A September and the sea even at mer minimum surface (roughly km?) remains ice-covered. the sea-ice cover much less the Southern Code Splitting for Web 2.0 Applications .

Some processes and equations involving the Cartesian system can become very complicated. You can simplify some of these by using Polar coordinates instead.
