Mathematical Relationships

Common mathematical relationships

Relationship	Signature	Ratio
linear	$y=x$	$\frac{y_2}{y_1}=\frac{x_2}{x_1}$
quadratic	$y=x^2$	$\frac{y_2}{y_1}=(\frac{x_2}{x_1})^2$
square root	$y=\sqrt{x}$	$\frac{y_2}{y_1}=\sqrt{\frac{x_2}{x_1}}$
inverse	$y=\frac{1}{x}$	$\frac{y_2}{y_1}=(\frac{x_2}{x_1})^{-1}$
