Introduction Direct variation, also known as direct proportionality, describes a specific linear relationship between two variables. By definition, the statement “y varies directly as x” may be expressed mathematically as follows: y=kx where k...
In this section, we will be looking at factors. When working with numbers, it is important to be able to do a number of operations on them. The basic operations are – multiplication, division,...
In this section you will be looking at Recurrence Relations. A Recurrence Relation is an equation which recursively defines a Sequence. You must be able to find the Recurrence Relation for a given Sequence,...
