Differential Equations MASH!

One word problem you will very commonly face in MA2051 is that of growth and decay! These problems all take on a very similar form and there...

Aside from remembering how to do various derivatives and integrals, in MA2051 there are some calculus topics you need to remember from earli...

As promised, here is the second method of solving first order equations. This method works only on linear equations - see my earlier post on...

First order differential equations are those that have a first derivative - y' or dy/dx - as its highest order derivative. There are t...

Again, I pulled formulas out of thin air when I showed amplitude-phase form. Your professor may want to see justification, so I will show an...

A few posts ago, I explained how to get answers for second order linear diff EQs. However, I just provided formulas. This isn't enough f...

One of the great things about Diff EQs is you can always check your answer. The checks aren't necessarily super easy, though, so I'd...
