pohjakaarre
Pohjakaarre is a Finnish term that translates to "polar curve" or "polar asymptote" in English, particularly in the context of mathematical curves. It refers to a line that a curve approaches as it tends towards infinity. In polar coordinates, a pohjakaarre is a ray originating from the pole (the origin) that the curve gets arbitrarily close to.
The concept is analogous to asymptotes in Cartesian coordinates, where a curve approaches a line without ever
To determine the pohjakaarre of a polar curve r = f(theta), one typically examines the limit of r
