Parametric HelpX = 2/t Y= 4t
a) Show that the tangent to C at the point P with the parameter p has equation
y = -2p^(2)x + 8p
Got to the equation, but b) I don't get.
b) The tangent to C at the point P passes through the point (2,3). Show that P can be one of the two points. Find the co ordinates of each of these two points.
Any help would be appreciated. -

Re: Parametric HelpOk, but what is P ?(Original post by TenOfThem)
Put those values in for x and y and you will have a quadratic in p to solve
I don't understand it. Is a point on the graph where it touches the tangent C? -

Re: Parametric HelpThe point P is at (1.5 , 0.5)?(Original post by Mr M)

Re: Parametric Helpone possibility for p = 1.5 and the other is 0.5(Original post by megafobia)
The point P is at (1.5 , 0.5)?
have you then found (x,y)
