Consider a point [math](x_1,y_1)[/math] on the graph of [math]b^2x^2 + a^2y^2 = a^2b^2[/math].

  • Find the slope of the tangent to the graph at [math](x_1,y_1)[/math].
  • Write an equation of the tangent line in (a).
  • Show that [math]b^2xx_1 + a^2yy_1 = a^2b^2[/math] is an equation of the tangent line.
