Title Inequality Solver 1
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 six inequalities, or six 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+2X-3)≤X+1, abs((X-3)(X+2))=4, (X^3-7)^(1/3)>X-1, √(7X-4)<7X-4, √(4X+3)+√(4X-3)>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.
