Did you know?
WebIf a point (at2, 2at) be the extremity of a focal Chord of parabola y2=4ax, then the length of the focal chord is Q. If a point ( a t 2 , 2 a t ) be the extremity of a focal Chord of parabola … WebThe variables are x (dependent variable that represents position) and t (independent variable that represents time). If you need to solve for t, there are a few ways to do that. You may find the quadratic formula to be easiest. Use t = instead of x = when setting the quadratic formula up. I used the quadratic formula method and it worked.
