Hint: the chain rule states that for y=u(x) ^a, the derivative will be dy/dx = dy/du * du/dxSo we just need to find dy/du and du/dx!In this case u(x)=x-3, so du/dx = 1.from y=u^(-3), dy/du = -3u^(-4).This...

In order to deal with the modulus sign, we must take account of 2 possible cases:

Case 1: |2x + 1| = (2x +1). In this case we can solve algebraicly, preserving the inequality sign, to get...

To solve this problem, we must first differentiate:

Identify that we are able to use the product rule as our expression is of the form y = f(x)g(x) where f(x) = e^(2- x) and g(x) = ln(3x-...

With History there is so much content and so much to say that it can be hard to work out what to include and what to cut out. Whether you have a word count or a time limit, it is important that your es...

Firstly, I would suggest re-reading the books/plays/poems that you are required to know. If it is a closed book exam then it is important that you know these texts inside and out. Focus on important th...
