5.3 Special Exponential and Logarithmic Functions
Special Exponential Functions
- The exponential function y=e^x is a special exponential function, and is vital in the field of mathematics.
- In particular, e=\lim _{n \rightarrow \infty}\left(1+\frac{1}{n}\right)^{n} is a constant known as the Euler’s number. It is approximately 2.718281459045…, and it is an irrational number like \pi.
