GCSE Bearings revision- Foundation/Higher

There are three important rules to remember when faced with a bearing problem:

1. Always start from north 
2. Always turn clockwise 
3. Write as 3-digits. e.g 035

Bearing problems are often worded: Find the bearing of B from A. This means you need to put your protractor on A and then measure the bearing to B, with zero facing north, going clockwise around your protractor and writing as three digits. 

Here is a video from corbett maths and some practise questions to have a go at.

When answering circle theorem problems, it is extremely important to use the correct vocabulary. The examiners are looking for certain key words, for example circumference, center, cyclic quadratic etc. Using the vocabulary in the post above from Corbett maths is important. 

Here are some practice exam questions and answers to have a go at!

Higher Vector questions.

Today we were working on some GCSE vector questions. Remember to clearly label your diagram and think carefully the direction you are going. Also, remember that in the exam you need to write    a to show it is a vector. 

This video from corbett maths shows how to answer vector questions and their are some questions below to have a go at.

Parallel and Perpendicular Lines

Get some practise in on finding perpendicular lines!

When it comes to perpendicular gradients, the key rule is that the gradients have a product of -1.

So, this means that if you know one gradient, the perpedicular gradient comes from changing the sign and inverting it - for example, a gradient of 2 is perpendicular to -1/2.

A couple more -

A gradient of -3 is perpendicular to a gradient of 1/3
A gradient of 2/3 is perpendicular to a gradient of -3/2

Still not sure? Take a look at this tutorial from Corbett Maths.

Changing the subject: Foundation and Higher

Make x the subject means rearrange the formula to make it  x= . It is important to take it step by step to make sure you done make any mistakes!

 Higher:

On higher, when you change the subject and you have x on both sides, you need to rearrange to get x on both sides first, the once you have x on the same side you need to factorise then divide. 

 

Here are some higher questions which can be found on our instagram account.
