An arithmetic sequence has a constant difference between each term. For example: 2,4,6,8,10,12,… We can see clearly that all the terms differ by +2. We call this the common difference, d. A geometric sequenc...

The quotient rule is a formula used to differentiate fractions that contain terms of x in both the numerator and the denominator (we usually refer to this as f(x)/g(x)). As it isn't possible to differentiate...
