The equations of two ellipses are i) 4x (squared) + 9y (squared) = 36 (ii) 2x (squared) + 3y (squared) = 30. A tangent to ellipse (i) meets the ellipse (ii) at the points P and Q. Show that the tangents at P and Q to ellipse (ii) are at right angles to one another. Please show this using parametric equations.© BrainMass Inc. brainmass.com September 19, 2018, 6:34 pm ad1c9bdddf - https://brainmass.com/math/geometry-and-topology/conics-problem-and-parametric-equations-prove-that-tangents-of-two-ellipses-are-perpendicular-46652
