From Cyd Disler:
MathCruncher is a neat app for high school math. It contains a large selection of calculators that can do geometry, algebra, and some trigonometry. Some of its features include:FactoringFinding Zeros from equation coefficientsSimplest Radical FormQuadratic EquationLogarithms2x2 and 3x3 DeterminantsArithmetic and Geometric SequencesSine, Cosine, Tangent and their inverses
-Improved the quadratic equation formula -Improved the simplest radical form calculator-Fixed a bug with the factorial calculator-Added 2x2 and 3x3 determinants -Added a calculator for determining zeros of a polynomial when given its coefficients. This is a test to see what people think. It will not return zeros that are not rational roots. Improvements to come soon.-Created system to change the number of inputs on screen to allow user to fit the inputs to their specific input. So far, only Find Zeros implements this feature, but well continue to work on more. Have no fear!-App-wide font change-Changed the animation of the drop down arrow-Added a general app settings menu that doesnt really do much right now, but adds a way to clear all favorites in case you want that. It also has a neat little About section.-Reorganized some of the calculator lists-Redesigned the calculator input screen to not use so much empty space.-Introduced a custom keyboard for calculator input-Input fields now allow math evaluations, so users can type 5+6*2 and that will be evaluated and used in the calculation.
