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...

How to solve a quadratic equation? While learning mathematics, you will often meet quadratic equations. These equations serve a mathematical way to say that a certain equation, which may resemble a real-life...

While simultaneous equation with two equations and two unknowns should be easy enough to solve using elimination, substitution, or graph sketching, simultaneous equations with more than two equations and two...

First off, write your equation in the form: ax^ 2 +by+c=0 with a, b and c being your constant coefficients. First, we will factorise out a such that: a(x^ 2 +(b/a)x)+c Now divide b by 2. Then write a(x+(b/2a...
