Equation of normal at (x_(1);y_(1)) in Parametric form slope form

The normal at any point P(x_1,y_1) of curve is a line perpendicular to tangent at the point P(x_1,y_1) . In case of rectangular hyperbola xy=c^2 , the equation of normal at (ct,(c )/(t)) is xt^3-yt-ct^4+c=0 . The shortest distance between any two curves always along the common normal. The number of normals drawn from ((7)/(6),4) to parabola y^2=2x-1 is :
