Morph curve depends on the parametrization of the circle
The form of the morph curve does depend on how the original curves are parametrized. Changing the parametrization of the original curves does not change their appearance when displayed, but it does change the appearance of the morph curve.
Caustic curve as focus of parabola
The red curve is f(x) (for -2≤x≤2). The blue curve is the terms up to the square term of the Taylor series. A is the vertex of this parabola, B is its focus. The orange curve is the caustic - envelope of the reflection of vertical rays reflected in a mirror aligned with f(x). Observe that the focus of the parabola traces the caustic.
Area Between The Curves
Find the area between two curves of your choice using calculus! Check your answer!
Curve Area
E is the midpoint of AD and F is the midpoint of BC. A closed curve is made by joining the cubic spline whose control polygon is EABF to the spline whose control polygon is FCDE. Can you identify a relationship between the area of the curve and the area of the polygon ABCD?
Tangents to Polar Functions
The purple curve has polar equation r=f(θ). A lies on this curve, and B is a point at the intersection of the tangent at A with the line perpendicular to OA. The red curve is the locus of B The grey curve is the curve r=g(θ) rotated by the quantity on the slider. What function g() will rotate to lie on top of the red curve?
Morph a circle into a square
Geometrically, the morph curve is constructed by joining two corresponding points on the original curves by a line, and then positioning a third point at a specific proportion along this line. Drag the middle red dot to see the morph curve change.
