Any straight line graph has a constant gradient, which is calculated by the change in 𝑦 divided by the change in 𝑥, along any section of the graph. The gradient is measuring the steepness of the ...

The study of Lagrangian equations and gradient estimates occupies a critical niche at the intersection of partial differential equations, differential geometry, and variational calculus. Lagrangian ...

A cornerstone of modern physics is mathematics. Like it or not, without the tools provided to physicists by mathematics, physics would be dead in the water. But (and this is something that all of us ...
