Many physical processes in fields such as mechanics, thermodynamics, electricity, magnetism or optics are described by means of partial differential equations. The aim of the present book is to demontstrate the basic methods for solving the classical linear problems in mathematical physics of elliptic...
Perform variable separation u=v+w , we can get this two equations:v_{tt}-v_{xx}=0,\ (x,t)\in\mathbb{R\times R^+}\\v|_{t=0}=0,\ v_t|_{t=0}=\cos x\\andw_{tt}-w_{xx}=t\sin x,\ (x,t)\in\mathbb{R\times R^+}\\w|_{t=0}=0,\ w_t|_{t=0}=0\\Use...
There are new methods of learning, new concepts to be tried, but the basic core of physics remains a constant in an ever-changing world. Mathematical Methods for Physics is the bridge that brings these two worlds together. With supplemental material such as graphs and equations, Mathematical Met...
