Re: any1 here good at maths?
ok i'm trying to work this out:
A curve has parametric equations
x = t(t − 1), y=4t/(1-t),
The point P on the curve has parameter t = −1.
the tangent to the curve at P has the equation
x + 3y + 4 = 0
The tangent to the curve at P meets the curve again at the point Q.
Find the coordinates of Q.
other info. dy/dx in terms of t is: 4/(2t-1)(1-t)^2
gradient of P is -1/3.
coordinates of P is (2,-2)
help me!

Ya... I am happy that all I really need to know is 1 + 1 = 2 and simple stuff like that!
