3. Numerically Solving PDE’s: Crank-Nicholson Algorithm
www.sfu.ca3. Numerically Solving PDE’s: Crank-Nicholson Algorithm This note provides a brief introduction to finite difference methods for solv-ing partial differential equations. We focus on the case of a pde in one state variable plus time. Suppose one wishes to find the function u(x,t) satisfying the pde au xx +bu x +cu−u t = 0 (12)
Maxima by Example: Ch.4: Solving Equations
home.csulb.edu4 Solving Equations Maxima has several functions which can be used for solving sets of algebraic equations and for nding the roots of an expression. These are described in the Maxima manual, Sec. 21, and listed under Contents under Equations . This chapter gives examples of the following Maxima functions:
A guide to Edexcel GCSE Mathematics (9-1)
qualifications.pearson.comAO3 is about solving problems with a much greater focus on solving non-routine problems in mathematical and non- mathematical contexts. 25% foundation 30% higher In 2015 there is less AO1 at Higher and roughly the same at Foundation compared to 2010. Quality of written communication (QWC) is also now included as part of AO2.
