Hey guys,
I did a projectile question and the concept of it was along the lines of using diffrentiation somehow to find the distance between the particle being projected and another object. It wasn't like a normal range question. But now i cant seem to find the question. Could someone please...
P is a variable point on the parabola [x^2 = 4y]. The Normal at P meets the parabola again at Q. The tangents at P and Q meet at T. S is the focus and QS=2PS.
(a) Prove angle PSQ = 90 degrees
(b) Prove that PQ = PT
Thank you :)
Hey guys I'm currently in year 11 and doing accelerated maths 2u and ext1. I'm worried that im not able to do well in my preliminary subjects. Should I be worried? How important is it to do well in prelims?
