Isabell van Ackeren,Klaus Klemm : ℝ → ℝ and . : ℝ → ℝ. We thus consider the initial value problem.where . : ℝ → ℝ and . : ℝ → ℝ are given functions, which we refer to as a . problem, because the right hand side . (.(.), .) separates into the quotient of one function .(.) of x only, and one function .(.(.)) of .(.) only according to (39.2).

Die Abwehr des Typhus bei den Feldarmeen,or . ∈ ℝ.. We recall that if . is non-singular with non-zero determinant, then the solution . ∈ ℝ. is theoretically given by Cramer’s formula. However if . is large, the computational work in using Cramer’s formula is prohibitively large, so we need to find a more efficient means of computing the solution.
