Hi!

I am researching to get a 991EX and wondering if it can do something like this:

value1 = sin A + sin B + sin C

value2 = cos A + cos B + cos C

I want to store the variables A, B and C and then run the two formulas to get value1 and value2. Then I get another set of A, B and C and run both formulas again to get the results. What is important is: I turn off the calculator and turn it back on, I still have the two formulas available to me and I can run immediately.

Also, I need to run those two in DEG mode. Can I input degrees like 20 degrees 17.4 minutes (note the minutes are not integer but a real number).

Thanks!
