A good approach to solve this is to use the chain rule of differentiation. The chain rule states: dy/dx= (dy/du)*(du/dx). In this case let u = 1+3x, so y = u^2. Then dy/du = 2u and du/dx = 3, so dy/dx = (2u)...

Everyone learns in different ways, but some of the most common ways of learning new vocabulary are explained below. Try the techniques to work out which way works best for you, and you can adapt it as necess...

Data response questions are either 4,6,8,10 or 14 marks. The marks awarded for each type of question are: 4 marks: K=2 Ap=2 6 marks: K=4 Ap=2 8 marks: K=2 Ap=2 An/diagram=4 10 marks: K=2 Ap=2 An/diagram=2 E=...

Always start the answer by defining the keywords in the question. You can gain up to 2 marks for definitions alone. Second, give a simple analysis of your answer. Transmission mechanisms are often a good way...
