This article continues from the previous article. It may be a good idea to read through it before attempting this. This article explores how to convert parametric equations into a Cartesian equation. We shall...
In the following series of articles we shall explore parametric equations in coordinate geometry. The following articles shall look at sketching the graph of a curve given its parametric equation, using the parametric equation...
Here are a few notes that are useful when working with algebraic expressions and functions. Remember you simplify an expression by collecting like terms You can also simplify expressions by using rules of indices...
This triangular based prism shown above has a triangle base. The area of this triangular base s ½ bxh and the perimeter of this triangular base is s1, s2, s3. Just add all the...
Here we have a circular based prism; It’s as though the prism has been extruded from the circle below the prism and that’s the general idea behind the prism surface area. The area of...
The following image shows a square based pyramid with labels. Deriving the Surface Area (SA) Let’s try to derive/prove the surface area pyramid above. It’s actually very simple. At the bottom of this pyramid...
The following image shows a sector in a circle. We can work out the area of a sector by relying on the fraction and percentage of the angle of the sector to the 360o...
A sector of a circle is a pie shaped region bounded by an arc and angle at the centre of the circle. Below the sector of the circle has been shown. And the formula...
There are many types of solid prisms. A prism is a solid shape with a uniform cross section. Below we shall be exploring these examples. Rectangular based prisms This is how you find the...
The following shows the shape of a cone; The volume of a cone is given by the following formula;
