Title

Inequality Solver

Description

This program is a multi purpose inequality solver. You can use all of the = ≠ > < ≥ ≤ signs. The program uses the solve( function and can find up to four inequalities, or four roots. If there are less of them, the program stops with an ERROR: NO SIGN CHANGE. Just press for QUIT then. For the program to work, the graph needs to cross the X axis at least once. So if you don't get an answer, press [ GRAPH ]. If the graph is entirely above, or below, the X axis, the answer should be for all X's defined, or for no X's, if it's an inequality. Otherwise you have no solution. Some statements it can handle: A*abs(BX+C)+D≥E, abs(X^2+2X3)≤X+1, abs((X3)(X+2))=4, (X^37)^(1/3)>X1, √(7X4)<7X4, √(4X+3)+√(4X3)>4. If the statement gives a continuous function the program can solve it if the function is differentiable in the proximity of its real roots.
