Exponential functions are very important in all branches of physics and mathematics. It is in fact taught in the very beginning when one learns mathematics.
In R programming exp(x) calculates, 'e to the power of x' where e is the Euler's constant.
Let us calculate the values of e raised to power of x, for x=0, 1, 10, and 100 using R.
How about exponential of negative numbers like, e raised to power of y, where y=-1,-10, and -100?
R can also be used to find expm1() which is defined as follows and should be used for small values of x instead of exp():
expm1(x)=exp(x)-1=(2*tanh(x/2))/(1-tanh(x/2))

For small x expm1() is better than exp() - 1
