A differential screw is a mechanism used for making small, precise adjustments to the spacing between two objects (such as in focusing a microscope, [2] moving the anvils of a micrometer, [3] [4] or positioning optics [5] ). A differential screw uses a spindle with two screw threads of differing leads (in case of a single lead equal to the ...
Stiff equation. In mathematics, a stiff equation is a differential equation for which certain numerical methods for solving the equation are numerically unstable, unless the step size is taken to be extremely small. It has proven difficult to formulate a precise definition of stiffness, but the main idea is that the equation includes some terms ...
Lagrange's identity (boundary value problem) In the study of ordinary differential equations and their associated boundary value problems, Lagrange's identity, named after Joseph Louis Lagrange, gives the boundary terms arising from integration by parts of a self-adjoint linear differential operator. Lagrange's identity is fundamental in Sturm ...

v. t. e. In mathematics and physics, a nonlinear partial differential equation is a partial differential equation with nonlinear terms. They describe many different physical systems, ranging from gravitation to fluid dynamics, and have been used in mathematics to solve problems such as the Poincaré conjecture and the Calabi conjecture.
It's also compatible with Bluetooth 4.1/4.2/5.0, IOS 12 or 13, Android 9 or 10. Surface Earbuds. Microsoft released wireless earbuds in 2019 that feature a "dish-looking apparatus" on the outside for touch interactions. The earbuds can also live transcribe a PowerPoint presentation from a connected computer.
