Derive the Equation of the Parabola with a Focus at (6, 2) and a directrix of y = 1.
Solution:
Focus at (6, 2) and a directrix of y = 1
Consider (x, y) as the point on the parabola
Distance from focus (6, 2) is √(x - 6)2 + (y - 2)2
Distance from directrix y = 1 is |y - 1|
Equation of the parabola will be √(x - 6)2 + (y - 2)2 = |y - 1|
By squaring on both sides,
(x - 6)2 + (y - 2)2 = (y - 1)2
Expanding using the formulas
x2 - 12x + 36 + y2 - 4y + 4 = y2 - 2y + 1
So we get,
x2 - 12x - 2y + 39 = 0
Therefore, the equation of the parabola is x2 - 12x - 2y + 39 = 0.
Derive the Equation of the Parabola with a Focus at (6, 2) and a directrix of y = 1.
Summary:
The equation of the parabola with a Focus at (6, 2) and a directrix of y = 1 is x2 - 12x - 2y + 39 = 0.
