Never mind I cant take a derivative
bk2 p41 q48
question : given the curve C: and P(h,k) is a point on C , where h and k are non-zero no.
(a)find the equation of the tangent to C at P
(b) if the tangent found in (a) intersects C again at Q , find the coordinates of Q.
my working:
equ.
sub to C
don't know how to solve and find Q
thanks!
