This question requires integration by parts, using the formula:

Integral(u dv) =  u v - integral(v du) 

This is applied to find the integral of Ln(x) by writing Ln(x) as 1 * Ln(x), u is then...

The best way to improve time management is by practising past papers. These can be found on your exam board website e.g. AQA, Edexcel etc. By completing a past exam paper under timed conditions you are pu...

With differentiation we should always begin with the "times by the power and take one from the power" rule. For example, to differentiate ax^b --> (a x b)x^(b-1)

So...

x=-1/7 or -1/3

y=-3/7 or 1/3

We know that angles on a straight line add to 180 degrees. Now imagine you have a triangle and the angles are called A, B and C. 

We can orientate the triangles so that we form a straight line. We ...
