WebOct 15, 2024 · Polar curves are a type of curve that can be found in nature, as well as in mathematical equations. There are many ways to tell the petals of a polar curve, but one method is to look at the symmetry of the curve. If the curve is symmetrical, then it is likely that there are two petals. WebRecall that the proof of the Fundamental Theorem of Calculus used the concept of a Riemann sum to approximate the area under a curve by using rectangles. For polar curves we use the Riemann sum again, but the rectangles are replaced by sectors of a circle. Consider a curve defined by the function \(r=f(θ),\) where \(α≤θ≤β.\)
WebFor some curves, one quick way of determining symmetry is to transform to polar coordinates: for instance, $$(x^2+y^2)^2=x^2-y^2$$ ... Yes, that's why I'm interested if there's a procedure to determine if a curve does have symmetry of some sort, since a curve having symmetry is exceptional.
