This statement explains the policy on calculators used during the exams in Analysis in M.E. I.
In principle, any real calculator is acceptable, but I need to draw the line somewhere between a calculator and a computer.
Exceptions may be made on a case-by-case basis.
The normal operations of a calculator, such as multiply, divide, add, substract, change sign, exponentiate, and the standard math functions as found on my Ti 30 Xa calculator (sin(h), cos(h), tan(h), exp, and their inverses) do not have to be explained.
Anything else must be step-by-step derived, showing all intermediate results. But feel free to check your derivations using your advanced calculator.
