The pole of the line lx+my+n 0
WebbHint: Use the concept of conjugate lines which states that two lines are conjugate if the pole of a point on the line lies on the other line. Find the coordinate of any one point lying on the line \[lx + my + n = 0\], then substitute the obtained point in the equation of polar for the given circle and then equate this equation to the given equation of line \[{l_1}x + … Webb5 apr. 2024 · Let the line be represented as L.
