【實用教育app】RK-89: Symbolic Graphing Calculator|最夯免費app-gigacircle

Welcome to version 0.9a of RK-89. RK-89 is the latest release in the most advanced graphing calculator suite available on the App Store. RK-89 introduces symbolic calculation features to the RKalk engine that already powers RK-83.We're dedicated to making sure your experience with RK-89 is absolutely unprecedented. This early release gives you access to the powerful new features offered by RK-89 and allows us to gather the crucial user feedback we need to keep RK-89 on the cutting edge. Count on the same fast-paced development schedule that thousands of RK-83 users already enjoy; expect updates as quickly as the App Store approval process allows.The already robust RKalk libraries include: - numerical integration and solvers - list and matrix manipulation - descriptive statistics - trigonometric and other standard math functionsRK-89 version 0.9a builds on this rock-solid foundation, adding these math and programming features: - conditions, loops, and boolean operators. - list creation. `seq(expression, variable, low, high, [step])` "seq(X^2,X,0,5)" ==> "{0,1,4,9,16}" - anonymous functions. `func(variable, value expression)` "func(X,Y,X+Y)->G", "G(3,5)" ==> "8" - symbolic integration. `integrate(expression, variable)` "integrate(X^2, X)" ==> "(1/3)x^3" - symbolic derivatives. `deriv(expression, variable)` "deriv(X^2, X)" ==> "2x"Version 1.0 will include arbitrarily precise calculation, symbolic limits, extensions to the existing programming interface, expanded symbolic calculus and statistics routines, and more.We need your feedback to keep improving RK-89.
