Question #40819

Difficulty: 8/10 | 🟢 Free

The Question

Let HH be a hyperbola whose horizontal and vertical asymptotes are given by the lines y=22y = 22 and x=22x = 22, respectively. Let DD be the diameter of HH that bisects a family of parallel chords having slope mm. The value of mm is equal to dydx∣(1,1)\left. \frac{dy}{dx} \right|_{(1,1)} for the implicit curve y2−3y+2x136=0y^2 - 3y + 2x^{136} = 0. If the diameter DD intersects the yy-axis at the point (0,β)(0, \beta), find the value of β\beta.

Why This Question Is Tricky

Common Mistakes

This question tests the conceptual bridge between implicit differentiation and the geometry of conics, specifically the locus definition of a diameter.

The primary trap lies in the slope of the diameter for a rectangular hyperbola.

Students often incorrectly assume the diameter shares the slope of the parallel chords (mm) or make a sign error when deriving the locus of midpoints, leading to the incorrect equation y−22=272(x−22)y - 22 = 272(x - 22) and the trap answer -5962.

By forcing the calculation of m=272m=272 via implicit differentiation, the problem ensures students cannot rely on standard form memorization and must reconcile the derived rate with the asymptotic center (22,22).
