A normal at P(θ) to the hyperbola x24−y21=1 has equal intercepts on – InterviewSolution

1.	A normal at P(θ) to the hyperbola x24−y21=1 has equal intercepts on the positive x,y−axes. If this normal touches the circle x2+y2=r2, then the value of 12r2 is
Answer» A normal at $P (θ)$ to the hyperbola $\frac{x^{2}}{4} - \frac{y^{2}}{1} = 1$ has equal intercepts on the positive $x, y -$ axes. If this normal touches the circle $x^{2} + y^{2} = r^{2},$ then the value of $12 r^{2}$ is
