Polar to Rectangular

In this video, I showed how to convert from polar to rectangular coordinates.

Thanks for this video. It is the first time that I am seeing polar coordinates written in the form of an equation. I usually see polar coordinates written as (r, theta), which means (radius, angle). I learned much from this video. Keep up the good work 👏.

... A good day to you Newton, In the Polar world (I can feel the cold ... (lol))(r^2)sin(2T) = 1 is just an ordinary orthogonal hyperbola y = 1/2x in René Descartes' world, this is amazing. Are you going to explore this topic a little more in the future? Short but strong presentation on polar-rectangular coordinates ... Thank you Newton, Jan-W p.s. I maybe would have added: Angle (Theta) = arctan(y/x) --> (x, y) (r, Theta) ...

Absolutely grateful. Yes I do plan to go further and to give full credit to Descartes for his invention. Thank you.
