WebDec 4, 2007 · This book describes methods of drawing plane curves, beginning with conic sections (parabola, ellipse and hyperbola), and going on to cycloidal curves, spirals, glissettes, pedal curves,... In geometry, a strophoid is a curve generated from a given curve C and points A (the fixed point) and O (the pole) as follows: Let L be a variable line passing through O and intersecting C at K. Now let P1 and P2 be the two points on L whose distance from K is the same as the distance from A to K (i.e. KP1 = KP2 = … See more Polar coordinates Let the curve C be given by $${\displaystyle r=f(\theta ),}$$ where the origin is taken to be O. Let A be the point (a, b). If $${\displaystyle K=(r\cos \theta ,\ r\sin \theta )}$$ is … See more • Conchoid • Cissoid See more Oblique strophoids Let C be a line through A. Then, in the notation used above, $${\displaystyle l(\theta )=\alpha }$$ where α is a constant. Then See more Media related to Strophoid at Wikimedia Commons See more

WebThe meaning of STROPHOID is a plane curve that is generated by a point whose distance from the y-axis along a variable straight line which always passes through a fixed point is equal to the y-intercept and that has the equation ρ = α(sec θ ± tan θ) in polar coordinates.

WebThe strophoids y^{2}=\frac{x^{2}(a+x)}{a-x}. in this video, we're gonna go through the answer to question number 10 jumped 16.3 to rest if I into the orthogonal trajectories of the family of curves. Why is equal to eat the K X work? A is a constant diverse. Once find the Grady in off the cars is equal to u k E X. Webconics of a confocal family is a strophoid. In descriptive geometry, strophoids appear as perspective views of particular curves of intersection, e.g., of Viviani’s curve. Bricard’s flexible octahedra of type 3 admit two flat poses; and here, after fixing two opposite vertices, strophoids are the locus for the four remaining vertices. roman of epoch times
