Answers to Questions

What is the exponential function? (Definition)

The definition of the exponential function is the solution of the equation $ f' = f $ with $ f(0) = 1 $, i.e. the function which is its own derivative and which has the value 1 at 0.

The exponential function is denoted by exp that is based on the number $ e \approx 2.71828\ldots $ (check also the decimals of the number e).

Example: $ \exp (7) = e^7 \approx 1096.633 $

The $ e^x $ notation is sometimes ambiguous, because $ e $ may be used as a variable, prefer using the $ \exp(x) $ notation.
