A stationary point is simply a point on a graph where the derivative=0. Ie, the rate of change of the curve at this point is 0 and therefore it is neither increasing or decreasing at this point . There are t...

The product rule can be used to differentiate a function that is formed of the product of two other functions; e.g f(x)=x 2 e x the product rule is as follows; if f(x) is split up into u.v (in this case u wo...
