Significant Figures
Rules:
1. Determination of number of significant figures.
a. Zeroes within a number are always significant
Ex/
1023 has 4 significant figures
10.01 has 4 significant figures
b. Numbers to show precision are always significant.

Differentiation and integration of simple functions
Differentiation:
You differentiate a quantity to see how an infinitesimally small change in one quantity
will affect the other. (For example, see how much y will change due to a small change in
x)
