Notes on the equation of a tangent to the ellipse
WebSolution We have to find the equation of tangent to the circle x 2 + y 2 – 2y = 0 at (– 1, 1). The equation of the tangent to the circle x 2 + y 2 + 2gx + 2fy + c = 0 at (x 1, y 1) is xx 1 +yy 1 + g (x + x 1) + f (y + y 1) + c = 0 Comparing the equation x 2 + y 2 – 2y = 0 with x 2 + y 2 + 2gx + 2fy + c = 0, we get, g = 0, f = – 1, c = 0 WebThe equation of the tangent to the ellipse x2/a2 + y2/b2 = 1 at the point (a cos θ, b sin θ) is x cos θ/a + y sin θ/b = 1. In terms of slope, the equation of tangent to ellipse x2/a2 + y2/b2 = 1 is given by y = mx ± √ (a2m2 + b2). In general, the line x cos c + y sin c = l is a tangent if l2 = c2 cos2α + b2 sin2α. firth vet store
