y = 4x^3 + 7 x

Recall: to differentiate any function of the form y = x^n

dy/dx = y' = n x^(n-1)

Hence if y = 4x^3 + 7x

dy/dx = 4 ( 3x^3 -1) + 7x^...

First of all look at the question: make sure you understand all the key words and that you know exactly what you are being asked. Then 1) give a definition of how you understand these key words 2) take...

To answer this question, it is first important to understand the meaning of the word degenerate.

So being an A level Biology student, you must know that genes code...

For example: 5x +25

In order to factorise we need to find a common factor for both '5x' and '25'. This factor gets taken outside of the brackets.

For this example the common ...

Recall: We treat inequality in a similar manner to the equal sign.

The steps are:

1. Collect like terms

2. Simplify

3x – 7 > 3 ...
