Find equations for the tangent lines and the normal lines to the hyperbola for the given value of x. (The normal line at a point is perpendicular to the tangent line at the point.) (a) tangent lines (smaller y-component of the two tangent points) (larger ycomponent of the two tangent points) (b) normal lines (smaller y-component of the two tangent points) (larger y-component of the two tangent points)
