3. Let P = (a cos θ, b sin θ), where θ is not a multiple of π/2 be a point on the ellipse (x 2/ a2 )+ (y 2/ b 2) = 1, where a ≥ b > 0; and let P1 = (a cos θ, a sin θ) the corresponding on the circle x 2 /a2 + y 2/ a2 = 1. Prove that the tangent to the ellipse at P and the tangent to the circle at P1 meet on the x-axis.
