Basic Curve Calculations Help

[Randy Hambright]

OK, my trusty little curve calc app on my phone died, so my question is where in the LS does a person simply fill in a couple of knowns and
the rest of the curve calcs show up, I know its simple, but cant put my finger on it.

Thanks

Cogo - Stakes - Arc should do it.
