Mathematical Methods & Applications
(sem 1 of 33098)
• Some revision of partial differentiation
See Tutorial 11, and Tutorial 11 Supplement on partial differentiation (from 1st year Maths). If you need revision of this topic, it is probably best to look at the supplementary tutorial first. Here is a pdf copy of Tutorial 11 and a link to the ‘clickable version’ of the Tutorial 11 Supplementary (in which you can click on the green bits).
