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…
