question_answer 1)

 Find the equation of the tangent and normal to the hyperbola  at (x0, y0).

Answer:

Given curve :             ?.. (1) Diff. (1) w.r.t. x               = slope of tangent to (1) at (x0, y0)              Equation of tangent to (1) at (x0, y0) is             y ? y0 = m (x ? x0)                                                  and equation of normal to (1) at (x0, y0) is
