# How do I work with Euler's number in Excel?

Jul 3, 2018

#### Explanation:

Excel has an exponential function and a natural log function.

The function is =EXP(value) and it gives the result of ${e}^{v a l u e}$ (this is called syntax). For example, to find the value of $e$, we can write =EXP(1). Further if we put a number $x$ in A1 and in A2 we put the formula =EXP(A1^2-1), this gives us ${e}^{{x}^{2} - 1}$.

In other words, whatever is in the exponent goes in the parentheses.

In other words if we put a number $x$ in A1 and in A2 we put the formula =LN(A1^2-1), this gives us $\ln \left({x}^{2} - 1\right)$.
