Hi I have an exercise and Iíve been struggling for a while with that. This is it:
Find coordinates of the focus and the equation of the directrix of the parabola whose equations is:
The chord which passes through the focus parallel to the directix is called the latus rectum of the parabola. Shown that the latus rectum of the above parabola has length8/3.
I do not understand this exercise at all. I have always thoughts that parabola equation looks like that:
y = 4x"squer" -4x +3
Anyone know how to resolve this problem?
