The Parabola Formulas The standard formula of a parabola $$y^2 = 2\,p\,x$$ Parametric equations of the parabola: \begin{aligned} x &=2\,p\,t^2 \\ y &= 2\,p\,t \end{aligned} Tangent line in a point $$D(x_0, y_0)$$ of a parabola $$y^2 = 2px$$ is: $$y_0\,y=p\left(x+x_0\right)$$ Tangent line with a given slope m: $$y = m\,x + \frac{p}{2m}$$ […]
