Differentiation can be done term-by-term, so we can treat the 5x³, -2x² and 2 separately. We can also 'take out' the coefficients: to differentiate 5x³, for example, di...

The problem with this fraction is the "i" on the denominator, it is not rational. To rationalise this fraction we use the complex conjugate.

This sounds more co...

The easiest way to solve this problem is by using differentiation.

dy/dx = (6x^2 + 4x + 2)/dx

dy/dx = 62x^1 + 41x^0 + 0

dy/d...

A bar-chart is a graph where the height of the bar measures the frequency of a particular category which that bar represents.

For a histogram, however, t...

The letters "x" and "y", or any other similar letter in an equation, are examples of unknown variables. 

What this means is that we don't know their v...
