In algebra, some problems can be solved by using a process of elimination. Work through this process with increasingly complex sample problems by identifying the question, determining the known and unknown information, and applying elimination. ...
The notation allowed elimination to be viewed as a sequence of arithmetic operations that were repeatedly optimized for hand computing and eventually were described by matrices. 展开 关键词: Algebra before 1800 Gaussian elimination Human computers Least squares method Mathematics education ...

J.H. Wilkinson put Gaussian elimination (GE) on a sound numerical footing in the 1960's when he showed that with partial pivoting the method is stable in the sense of yielding a small backward error. He also derived bounds proportional to the condition number $\\kappa(A)$ for the forward...
Linear equations are commonly used to solve problems involving two unknowns. By representing the problem with two linear equations, you can determine the values of the unknown variables by finding their intersection point. This method, known as the substitution or elimination method, allows for solvi...
