Evaluate the following definite integrals as limit of sums.`int_-1^1 e^x dx`

Explanation

Here, the function ` e^x ` is continuous in `[-1,1]`. since dividing the n length of `[-1,1]` in the same length,the length of each subset is `h`


i.e., `h=(b-a)/n=(1-(-1))/n=2/n`


`=>nh=2`


Here `a=-1 " and " b=1`
