Joseph J. Kohn, Who Broke New Ground in Calculus, Dies at 91 The techniques he developed in the field of complex numbers have found use in tackling a wide range of fundamental equations in physics.

The method of characteristics for solving first order quasilinear equations will be discussed. The three main types of linear second order partial differential equations will be considered: parabolic ...

Current equations for estimated glomerular filtration rate (eGFR) that use serum creatinine or cystatin C incorporate age, sex, and race to estimate measured GFR. However, race in eGFR equations is ...

An intermediate level course in the analytical and numerical study of ordinary differential equations, with an emphasis on their applications to the real world. Exact solution methods for ordinary ...

How to Graph Simultaneous Differentials in Excel. Differential equations are equations that contain derivatives. The equations are used in calculus to describe relationships among one or more ...

The honor, like a Nobel Prize for mathematics, was given this year to Luis Caffarelli for his work on partial differential equations.

Thanks to these abilities, they can already topple complex linear differential equations exponentially faster than classical machines. Researchers have long hoped they could similarly tame nonlinear ...
