Firstly, at GCSE it is possible to follow a very rigid structure and receive very high marks. You should write a very brief introduction and about 3 paragraphs with a conclusion that links and prioritises...

yes. firstly , we needs to solve what 5.2 x 10 is. This will give us a number to then compare to 34. so , to solve 5.2 x 10 we must remember that the multiply sign means the number will get bigger. since ...

Since x=5+i is a solution to f(x)=0 we then know that x=5-i must also be a solution to f(x)=0, by the complex conjugate root theorem.Now we can break f down into the product of a polynomial and these two ...

Hi! In question your examiners will be looking for a few main components, make sure you demonstrate them: 1) Can you use a variety of tenses 2) Do you have the appropriate vocabulary (in this case, use vo...

For a turning point, the differential of the curve is equal to 0. Therefore dy/dx = (12)x^(2-1) - (61)x^(1-1) + 0 = 0. This gives x = 3. Substitute this back into the original equation to get y=-...
