writing regular text in complex math expression in latex

Question

Hi everyone,

Right now I'm writing this expression where I would like to have the term "net" text.. and not italics, otherwise it implies n*e*t.. I don't know how to do this.. can someone help me fix my latex expression here:

f_i^{s*}(net_i(t)) = \frac{1}{2}(1+\tanh(\lambda net_i(t))

Answer 1

You can use \text{net}_i.

Answer 2

If your LaTeX distribution does not know the command \text, try \mbox{net}_i
