Many students at first will incorrectly separate the fraction into two fractions in the form of A/(x + b) + B/(x + b). If we then multiplied the two back together we will find that it does not equate to t...

For this we require the distance-speed-time triangle which is defined as follows:speed = distance/time.However for the we need to convert the time into hours as that's what the question requires.there is ...

The part of syllabus covered by this question is proof by contradiction. Consequently, in order to achieve a contradiction, you can assume that root2 is rational and thus expressed as a/b where a and b ar...

1.differentiate the equation using the rule: y=xⁿ , dy/dx= nx^n-12.set dy/dx to =0 as this is where a minimum point occurs (where the gradient of the graph is = 0)3.solve for x4.then,...

Completing the square of a function is sometimes used to find the stationary points on a curve, and also to solve when equaling zero. To complete the square firstly we have to halve the middle value of th...
