Significant figures
Rounding off numbers to a certain degree of accuracy is often necessary in many applications. For example 5,625,000 can be rounded off to one significant figure to make the figure simple or easy to...

Sketching Graphs
In this topic we shall be exploring how to draw graphs. But before we do that let’s look at the different types of graphs that you can sketch. You must know these graphs by...
Gradient of a Straight Line
The gradient is the result of the division between the length on the y-axis and the x-axis covered by the line or very simply the value representing the slopeness of the line. Here we’re...
Integration by substitution
One form of integration is the integration by inspection method which I have covered here. It might be best for your benefit to go through that revision before attempting this reading, it might make...
Area between a curve and the y-axis
Before attempting this maths learning it might be a good idea to go through the lesson of finding the area below the curve along the x-axis, because I won’t cover the basics and the...
Representation of Data
This is a quick lesson about representation of data. I thought I publish it since I haven’t posted for a while. These are really just basic facts about representation of data. There are two...
Differentiation of Logarithmic Functions
You can find derivatives for logarithms functions as well. Here is the first rule that will help you when working with such functions. It will be best to your advantage to be very familiar...
Equation of a normal to a curve
You must have a general understanding of graph gradients, tangents, normals and derivatives. This would probably be a reminder rather than a lesson. You must know that a normal is perpendicular to the tangent....
Equation of a tangent to a curve
You must have a general understanding of graph gradients, tangents, normals and derivatives. This would probably be a reminder rather than a lesson. Finding the equation of a tangent to a curve involves finding...
Surface Area of a Cylinder
The surface area of a Cylinder can be given by: This is because for the top and bottom parts the area is πr2 and the side cover/part is 2πrh
