Easter Sunday Trigs ( rpn38-CX)

[bshoring]

Thanks, Gerson for the programs and explanations. It is interesting that we can use the Net Present Value on a financial calculator to compute sine, up to a point, but as you say, the closer one gets to 90 degrees, the less accurate that method is.

I'd say that the best program is the one you posted on 3 April, 2016. It appears to give the best overall accuracy for the 6 main trig functions. This exercise has been quite an enlightenment for me.

Thanks!
