How do I differentiate?
Differentiation is a relatively easy process once you learn the basic method. The basic rule is, you multiply the coefficient of x by the exponent, which becomes the new coefficient, and then reduce the exponent by 1.
For example; differentiate 4x3
To get the new coefficient you times to old coefficient and exmponent together, in this case 4 x 3 = 12.
To get the new exponent, you reduce the old exponent by 1. So the new exponent is 3-1 = 2.
Therfore, the differntial of 4x3 is 12x2.
