Hi, I'm a newbie.

Okay, I'm sorta struggling with this question:

P is a point on the parabola x^2 = 4ay

The tangent at P meets the axis at T. If the focus is at S, show that SP = TS.

I have gathered the following coordinates:

P = (2ap, ap^2)

T = (ap, 0)

S = (0,a)

Unfortunately, when I used the distance formula, it shows that the 2 lines are not equal.

Does anyone have a clue how to do this?

Thanks

yeah.. I know this is a simple question (yet I can't solve it!).. please.. nice comments only. I've been attacked on other forum websites before, because of my stupidity
