About me

Hi,

My name is Dario, I am a postgraduate student in Computer Science at The University of Manchester. Previously, I have attained a First Class BSc in Computer Science at Sheffield University. I offer tutoring in Computing/Computer Science (and any related programming discipline) and Maths at GCSE, A-Levels and IB.

I am also bilingual in Italian and English and can therefore offer language tutoring and help develop linguistic skills.

I have previous experience teaching in Sixth-Form colleges and primary schools and have previously tutored students at different levels.

Please get in touch and we can discuss how best we can structure your program. I am very flexible with times and sure we can find slots that integrate well into your schedule.

Really good tutorial Dario, sorry I think the last time I filled this in I hadn't read properly what this was for so apologies for that! Your explanations are always very clear and the fact that you answer even badly formed questions by giving detail around the topic is great - it saves me coming unstuck when I try to use it in practice. My only minor gripe is the audio quality sometimes, which means I have to process things in my head a little to get catch what was said but I'm not sure if that is fixable and it's not a major problem anyway. I have a bit more spare time this week so I'll be writing notes on the lessons so far and trying to write a program to sort a csv file by given column, so I may have some more specific questions next week.

Solving absolute value inequality

For which values of x does the following inequality hold true:

 

(|x|+2)/(|x|-3) < 4

The first thing we want to do is eliminate the fraction on the left-hand side (LHS) of the equation. We do so by multiplying both side by |x|-3, leading to:

 

|x|+2 < 4(|x|-3)

We can simplify the right-hand side (RHS):

|x| + 2 < 4|x| - 12

We now want to group like terms together. As such, we will move all |x| terms to the RHS, and all integer terms to the LHS.

2 + 12 < 4|x| - |x|

14 < 3|x|

We now divide both sides by 3 to eliminate the coefficient of |x|

14/3 < |x|

or

|x| > 14/3

 

Now, imagine a number line...

 

<---- -x ------- 0 ----- x --------->

I would like you to remember the definition of |x| (absolute value) which indicates the distance of a value x from 0. (In other words, it makes any negative number positive and leaves any positive number positive)

This suggests that any x > 14/3 will satisfy |x| > 14/3.

However, we also have to remember that any value inferior to -14/3 will also satisfy the inequality.

As such, we solve the solution as

x > 14/3 OR x < -14/3
