Under the hood, mathematical problems called partial differential equations ... second-order parabolic PDEs explain how phenomena can become smooth over time. The most famous example in this ...

A straight line is a linear graph. A quadratic graph has an equation which includes an \(x^{2}\) term. Examples of equations that form quadratic graphs: \(y = x^{2}\) \(y = 3x^{2} + 2x – 5\) \(y ...
