A quantity may be a scalar (just a magnitude, just a number) or a vector, with magnitude and direction. For example, speed is a measure of how fast something is going, but velocity is a measure of how fast s...

y=3x 4 -8x 3 -3 Let's say we want to calculate dy/dx. For a term A x n , the differential with respect to x is An x n-1 . For a constant value, we can say that n=0 because x 0 =1. This means that when you di...

This is an example of an arithmetic series because each term is +4 from the previous term.This means for the "nth term" we start with +4n.Now we take a specific term from the sequence e.g. 3 (1st t...
