How to figure out a parabola equation
WebYou have to use calculus to get this function, but let us just say that for the equation y = ax² + bx + c, the slope is the function m = 2ax + b If you set that equal to 0 and solve for x, then you have to point in the parabola with zero slope. That will be: 2ax + b = 0 2a x = - b x = - … WebExample 1: Find the length of the latus rectum whose parabola equation is given as, y 2 = 12x. Solution: y 2 = 12x ⇒ y 2 = 4 (3)x Since y 2 = 4ax is the equation of parabola, we get value of a: a = 3 Hence, the length of …
