1. Start by simplifying the denominator  

          - We can write sqrt(12) as sqrt (4*3). 

          - This can be written as sqrt(4) * sqrt(3) 

          - We know the squ...

Expanding Rsin(x + a): Rsin(x + a) = Rsin(x)cos(a) + Rcos(x)sin(a) Comparing coefficients of sin(x), cos(x) with first expression leads to: Rsin(a) = 2, Rcos(a) = 5 Dividing these equations gives: tan(a) ...

The first step is to read and re-read the question. Work out EXACTLY what the question is asking you for, and what the examiner might want. Remember, you get marks for content, accuracy and structure. The...

I would use the x-y graph to explain the multiplication of negative numbers

I would also start with 4 x 3, then work my way towards negative numbers, e.g 4x2, 4x1 ......4x-1, 4x-2

Then I wou...

Essentially, there are four main channels of comparison. Form, structure, language and historical/literary context. It is important to highlight the similarities between the unseen text and your wider rea...
