Differentation is a type of calculus that allows us to work out the rate of change. For example, if we have a straight line graph such as y=2x, we know that the gradient of the line is 2. If we take a ...

x²+x-6=y

Is the equation we will use to demonstrate how to factorise quadratics.

The first step involves using the basic shape of all quadratic f...

e^{(x^2+2)}=f(x)=y

Is the equation we will use to demonstrate correct use of the chain rule.

The equation at the core of the chain rule is:

...

First differentiate the function:  y = f(x)   =>   dy/dx = f'(x)

Then set dy/dx = 0 and find the solutions. i.e. solve 0 =  f'(x)

For each value of x that is a solution, ...

Firstly, understanding how to construct a histogram will make understanding the Normal Distribution aka Gaussian Distribution much easier.

It is still an arrangement of a d...
