equation of normal to hyperbola in point form

Equation of Normal to hyperbola : \(x^2\over a^2\) – \(y^2\over b^2\) = 1 (a) Point form : The equation of normal to the given hyperbola at the point P(\(x_1, y_1\)) is \(a^2x\over x_1\) + \(b^2y\over y_1\) = \(a^2+b^2\) = \(a^2e^2\) Example : Find the equation of normal to the hyperbola \(x^2\over 25\) – \(y^2\over 16\) = …
