The product life cycle is a business marketing tool in which it is able to assess the stages a product goes through in its life. The four stages are 1. Introduction - Where the product is introduced to the m...

Factorising quadratic equations This method is used for the following factorable expression: ax 2 +bx+c Although this method is particularly useful with quadratic expressions with a≥2, it can be also used wh...

This is an integral many people struggle with, but, with a simple trick it becomes a little more straight forward. We will approach this integral using integration by parts. But what are the parts? Well, we ...

Take a matrix A=( a c b d ), where a,b,c,d are numbers. First find the determinant. This is a d-b c. Now, rearrange the matrix to become ( d -c -b a ). Divide this by the determinant, to have A -1 = 1 / (ad-...

This will use the process of integration by parts. First, notice that ln(x)=ln(x)*1. So, the integral of ln(x) is the integral of ln(x) 1. The process of integration by parts is; int (v du / dx ) dx =vu - in...
