## Conic Sections Formulas

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: $$y = m\,x + \frac{p}{2m}$$ […]

## Hyperbolic functions

Definitions of hyperbolic functions $$\sinh x=\frac{e^x – e^{-x}}{2}$$ $$\cosh x=\frac{e^x + e^{-x}}{2}$$ $$\tanh x=\frac{e^x – e^{-x}}{e^x + e^{-x}} =\frac{\sinh x}{\cosh x}$$ $$\mathrm{csch}\,x=\frac{2}{e^x – e^{-x}} = \frac{1}{\sinh x}$$ $$\mathrm{sech}\,x=\frac{2}{e^x + e^{-x}} = \frac{1}{\cosh x}$$ $$\coth\,x=\frac{e^x + e^{-x}}{e^x – e^{-x}} = \frac{\cosh x}{\sinh x}$$ Derivatives \( \frac{d}{dx}\, \sinh x = \cosh […]
