Introduction: This program has a lot more features than the built-in calculator, including an advanced screen display and full fraction, hex and binary support. The history list provides easy access to previous calculations and results, and a hotlist is provided for frequently used calculations. A live calculation feature displays the answer to an expression as you type in real-time, and an evaluate option simplifies entering complex calculations. Q-Calc uses advanced display techniques to show expressions the same way they are written, with powers as superscripts, stacked fractions and square roots drawn around numbers. It also supports multiple zoom levels. Expressions can be exported as sketch files, so Q-Calc also works as an equation editor. The built-in utilities will solve triangles, simultaneous equations and quadratics, find gradients, and convert between rectangular and polar coordinates. The matrix calculator can multiply, add, subtract, divide, transpose and invert. The integrated function grapher supports up to six graphs simultaneously. It will find y values, intersects, minimums and maximums, and calculate gradients and the second derivative. The graph editor has the same editing features as the calculator. The program offers a choice of color and line thickness for each graph. Graphs can also be exported as sketches.
