## Writing the softmax function

We need to write the `softmax()`

activation function to complete forward propagation. As it turns out, we can implement `softmax()`

in two lines of code—but those two lines require some attention.

Here is the mathematical formula of the softmax:

$\large{\text{softmax}(l_i) = \frac{e^{l_i}}{\sum{e^l}}}$

And that formula converted to code:
