Linear equations with one unknown Step by Step Solution Rearrange: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 27*x-(58)=0 Step by step solution : Step 1 : Solving a Single Variable Equation : 1.1 Solve : 27x-58 ...
Systems that are below prompt critical are considered, and the linear time-dependent neutron transport equation in a quite general setting is studied. Both source and cross sections are allowed to depend on space, energy, and time. The method of matched asymptotic expansions is used to find an...
which are linear or non-linear according to the nature of the partial differential equation(s) from which they are derived. In the non-linear case, the discretized equations must be solved by an iterative technique that involves guessing a solution, linearizing the equations about that solution,...

According to Exercise 3, similar matrices have the same trace. Thus we can define the trace of a linear operator on a finite-dimensional space to be the trace of any matrix which represents the operator in an ordered basis. This is well-defined since all such representing matrices for one ...
