ramanujan.math.trinity.eduNeumann Boundary Conditions Robin Boundary Conditions Remarks At any given time, the average temperature in the bar is u(t) = 1 L Z L 0 u(x,t)dx. In the case of Neumann boundary conditions, one has u(t) = a 0 = f. That is, the average temperature is constant and is equal to the initial average temperature.

The Chinese Remainder Theorem - ramanujan.math.trinity.edu
ramanujan.math.trinity.eduThe Chinese remainder theorem (CRT) asserts that there is a unique class a+ NZ so that xsolves the system (2) if and only if x2a+ NZ, i.e. x a(mod N). Thus the system (2) is equivalent to a single congruence modulo N. Although we only proved one implication, one can actually show that the …
