The locus of a point P (a, ß) moving under the condition that the line y = ax + ß is a tangent to the hyperbola x2/a2 -y2/b2= 1 ?

Hello student,

Tangent to the hyperbola isx²/a² -y²/b²= 1
y = mx ±
Given that y = αx + β is the tangent of hyperbola
⇒ m = α and a²m² –b² = β²
∴ a²α²– b² = β²
Locus is a²x² – y²= b² which is hyperbola.

Thanks and Regards
