The first step in scoring full marks on this typically 4 mark question is to recognise what it's asking you to do. We use the process of differentiation to solve it. f(x)=2x^3 - 2x^2 + 8xf'(x) = 6x^2 - 4x...

We need to split the initial fraction into two. We know that (x-5)/(x+1)(x-2) is equivalent to A/(x+1) + B/(x-2). Multiplying by (x+1)(x-2) we get x-5 = A(x-2) + B(x+1). Expanding the brackets gives x - 5...

Patrick Süskind frequently uses religious references in order to disparage society and the value it places on outmoded conventions. One way he does this is by highlighting the importance placed on virgini...

Light travels as waves which have a distinct set of properties: a speed, a frequency and a wavelength. These properties are related to each other through the following equation: speed = frequency * wavele...

Immunity is the capacity of the body to recognise the intrusion of disease-causing microorganisms (pathogens) and develop a response to fight infection. Antigens and antibodies are crucial to the process ...
