Contour Plot/Examples

Examples of Contour Plots

Arbitrary Example

This is a contour plot of the real function $f$ of $2$ variables defined as:

$\forall x, y \in \R^2: \map f {x, y} = 4 x^2 - \dfrac {21 x^4} {10} + \dfrac {x^6} 3 + x y - 4 y^2 + 4 y^4$

for various values of $f$ between $-0 \cdotp 8$ and $10$.
