Description
Just another mobile phone calculator, right? Wrong! :) Equivalence is a fully featured expression evaluator written from the ground-up. It includes many of the features found on regular scientific calculators plus more advanced features such as the ability to compute differentials and indefinite integrals. Expression entry was designed to mimic the way in which one does it on paper to facilitate ease of use. High contrast colour scheme allows for maximum visibility under any lighting condition.

Usage Instructions

Any derivative entered (and which is solvable) can be calculated using the ‘dy/dx’ key. Please use ‘x’ and ‘y’ keys to indicate variables. First input the expression you wish to have the derivative of computed (including variables) then press the ‘dy/dx’ key. The integral key ‘∫’ can be used to compute most solvable indefinite integrals. Please use ‘x’ and ‘y’ keys to indicate variables. More instructions available however unfortunately not enough space to type them here.
