## Why some people dislike maths

It’s not surprising that some people learn to hate maths.

Here isĀ  an article which talks about how poor teaching can sometimes cause ongoing problems. It’s just not fair that artistic people are frequently denied good explanations of mathematical concepts.

## Techniques for adding the numbers 1 to 100

The young Gauss was so smart and mathematically intuitive, he must have been a nightmare to have in class…take a look here.

## Why is e^(pi i) = -1?

The explanation you are looking for is here.

## Central limit theorem

The central limit theorem is pretty cool and is outlined here.

So
toss a coin 100 times
count 1 for each head and 0 for each tail

now repeat all of the above say 200 times

the 200 sum values will be distributed normally

eg
Sum/ Number of occurrences
2 /…3
10 /…..5
15 /……..8
23 /…………12
32 /……………………23
41 /……………………………..35
52 /…………………………………………….50
65 /………………………..29
73 /……………15
75 /……….10
82 /….4
93 /….4
95 /.1
100 /.1

## Maths anxiety?

It turns out that if to recognise and accept that you are anxious about maths, you can deal with the problem and go on to excel in the subject.

Here is one paper which discusses the issue and here‘s a later one.

## Binomial theorem

Can this get any more fun…?

Here is some stuff about the binomial theorem.

## The exponential function

This is a good place to grasp exponentiation and marvel at Euler’s formula.

## Differential equations

What happens when the rate of change of x depends on the value of x itself?
