MAT210 Lesson 16: Newton’s Divided Difference
An alternative way to find a polynomial approximation of a function is something of a mix of using the Taylor Series and numerical differentiation. Newton's Divided Difference method results in…
Statistics using spreadsheets
A student asked how to work a problem with the sample distribution of Pearson's r using a calculator alone. It involves using a z-table, but so many tools are available…
MAT210 Lesson 15: Direct Interpolation
In Numerical Analysis, our interest is not just interpolation of values, but interpolation of functions. Interpolation of functions means approximating a complex or unknown function with a simpler function, which…
MAT113 Workshop 26th & 27th May
We often encounter a problem that someone has solved partially and we only need to complete the work and report the results. That is our exercise today, using a partially…
MAT210 Tutorial #1: Errors, Differentiation & Roots
To wrap up the first three modules: Errors (Kaw ), Numerical Differentiation (Kaw Ch. 2), and Root Finding (Kaw Ch. 03), work on the tutorial found at this link on…
MAT210 Workshop 20th-21st May
We saw that a spreadsheet is a reasonably easy way to perform numerical differentiation. In our last workshop, we created - almost from scratch - a spreadsheet to compare the…
MAT113 Workshop 19th & 20th May
Objective Communication to a wider audience is most often done through reports or presentations, so knowing how to copy work done in one application into another application is valuable. This…
MAT210 Workshop 13th-14th May
A spreadsheet is a reasonably easy way to perform various numerical methods, especially differentiation. In our workshop, we will create - almost from scratch - a spreadsheet to compare the…
MAT113 Self-study Exercises
NOTE: Today work on the two exercises handed out yesterday. 1) Matrix in Spreadsheet 2) Re-using work in a spreadsheet. Go to MAT113 on Dropbox to download the sample spreadsheet…
MAT210 Numerical Analysis
Objective To equip students with an understanding of numerical methods for problem solving in various areas, especially how to analyze their suitability, accuracy, efficiency, convergence and stability. Delivery: 30 lectures,…
