Difficult# Producing Widgets: Tending to Infinity

SVCALC-7BFA3M

Wendy's Widget Shop (WWS) makes and sells widgets. A widget sells for $\$1,000$. WWS's operating costs are $\sqrt{n^2-n}$ thousand dollars, where $n$ is the number of widgets produced. Assume that every widget produced is sold.

As the number of widgets produced goes to infinity, what is WWS's profit?

Profit is defined as revenue minus costs.
