Find the coordinates of the point of intersection of tangents at the points where x + 4y –14 = 0 meets the circle x2 + y2 – 2x + 3y – 5 = 0.
Equation of the given circle is
x2 + y2 – 2x + 3y – 5 = 0
polar of P(x1, y1) is
Equation of QR is x + 4y – 14 = 0 –––(2)
Comparing (1) and (2)
y1 = 9/38
∴ Co- ordinates of p are (109/76,9/38)
