First of all, these questions aren't as scary as they look, you just have to think about it. You can work every question out in nice, easy steps. First, label the sides of the triangle A, B and C (you can see how to do this on the diagram to the left). Then you have to follow the formula a^2 + b^2 = c^2. This means that 'a' squared (so a x a), plus 'b' squared (b x b) equals 'c' squared (c x c) The problem is that you don't want to find 'c' squared, you just want to find 'c'. To do this you do the square root of 'c'. For the answers to questions 1-3 scroll down to the bottom of this page.

1. Remember to LABEL your sides A, B and C- they won't do it in the exam. 2. Always write out the FORMULA- it will help you remember that you can manipulate it like any other formula. 3. Make sure you actually KNOW what YOU have to do before you start the question- there is no point in working out something irrelevant.

Question 1. =2.3m c sq - b sq = a sq 4.7sq - 4.1sq =5.28 sqr 5.28 = 2.297 2.297 to 1 decimal place = 2.3m Question 2.=4.5cm a sq + b sq = c sq 2.3 sq + 3.9 sq = 20.5 sqr 20.5 = 4.527 4.527 to 1 decimal place = 4.5 Question 3. = 4.1mm c sq - b sq = a sq 8.9 sq - 7.9 sq = 16.8 sqr 16.8 = 4.0987 4.0987 to 1 decimal place = 4.1

Have a go at these questions and check your answers' below. If you're struggling, have a look at the 'Helpful Hints for Pythagoras'.

Remember this is a NON-CALCULATOR paper!

1) Unit C is a calculator paper, so make sure you know the necessary formulas to get your answer, there's no point trying to work something out if you can't use your calculator properly! 2) Make sure you write ALL your WORKING OUT down: it might seem silly but it can get you marks, even if you get the final answer wrong! 3) Get enough revision done and make sure it's effective! Don't just read your revision guide if that's not how you remember things, make flash cards or quiz yourself to make sure those facts stay in your head!

What is 'standard index form'? Standard Index Form is a way of writting very big, or very small numbers in an easy to read way. There are three rules you must learn before you can tackle any Standard Index Form question, they are: 1)The front number must be between 1 and 10 2)The power of 10, n, is just how far the decimal place moves 3) 'n' is positive for big numbers and negative for little numbers. (If you forget these rules when you're working out the questions, make sure you keep checking them so you know them for your exam)

1) What is 15 000 000 in standard index form? 2)What is 700 000 000 in standard index form? 3) What is 3.5 x 10 to the power of 7?

Before you can start learning the trigonometry you'll need for Unit C, you need to make sure you're familiar with it from Unit A- if you can't remeber read through the boxes below and make sure you check you understand.

If you follow the rules of trigonometry you can't really go wrong and the basic rules are easy to follow: 1) Always label the sides. (see the image to the left to work out what each side is called) 2) Put the values of each side into the formula triangle (see right)

If you want to do a bit more revision on any of these subjects have a look at the websites below- they will really help you.

These formula triangles will help you to remember how to work out trigonometry questions. All you have to do is put in the values you get given. The important thing to remember is when you divide two sides you must do the rule to the minus 1! You will have a button on your calculator to do this.
