1. 1. Write a short paragraph about the number (e). The origin of
this number, the properties of natural exponential function f(x)
= e^x
2. Write about the properties of definite integrals, the relation
between under the graph of the function and the integration.
Give examples to prove your ideas. Use the graph of each case
to prove your point of view.
