Final answer:
A parabola calculator using focus and directrix is a tool that helps you find the equation of a parabola given its focus and directrix.
Step-by-step explanation:
A parabola calculator using focus and directrix is a tool that helps you find the equation of a parabola given its focus and directrix.
To use this calculator, you need to know the coordinates of the focus, which is a point on the parabola, and the equation of the directrix, which is a line that is perpendicular to the axis of symmetry of the parabola.
By inputting these values into the calculator, you can obtain the equation of the parabola in the form y = ax^2 + bx + c.
