Focal length of parabola calculator
WebThen you substitute the parabola's equation into the rotation equations: y = k* x^2 x' = x * cos (theta) - (kx^2) * sin (theta) y' = (kx^2) * cos (theta) + x * sin (theta) Theta is a known value, and everything else is given in terms of x, so you can use this information to … WebSimplifying gives us the formula for a parabola: x 2 = 4py. In more familiar form, with "y = " on the left, we can write this as: `y=x^2/(4p)` where p is the focal distance of the parabola. Now let's see what "the locus of points equidistant from a point to a line" means. Each of the colour-coded line segments is the same length in this spider ...
