Firstly, everything here will just be me talking to myself and I am not spotting any trends. Functions, good to know how to do piecewise composite functions. Checking for inverse algebraically. [...]

Many students of mine have asked me this question numerous times. Some lamented that they work really hard, finishing off the revision package timely. However, they still cannot improve from a [...]

Let us look at the difference between modal value and expected value. We shall start by saying they are different, albeit close. Modal value refers to the mode, that is, the value that has the [...]
