Built-in functions, constants and units with search.Decimal, binary, octal and hexadecimal bases A computer is capable of performing calculus with large numbers and complex expressions in less than a second, thus helping in most domains of activity to also deliver accuracy. Features: Basic arithmetic (+, -,, /) Trigonometry (sin, cos, tan, arcsin, arccos, arctan) Complex numbers (5+7i) Graphs functions (YX2) Hexadecimal and.Fixed decimal, scientific or engineering formats.Expression editing with system virtual keyboard.History stack with value or expression recall.The imaginary unit is now available under the name j: j2 -1 (5+3j)/(8-2j) 0.5+0. To use them, make sure that the menu item Settings Behaviour Enable Complex Numbers is checked. Calculations with up to 50 digits of precision SpeedCrunch supports calculations involving complex numbers.
SpeedCrunch is a high-precision scientific calculator supporting expression editing, history stack, unit conversions, radix systems, complex numbers and user defined variables. Donated to support the maintenance of this app in F-Droid.The original app author has been notified.The app is not already listed in the repo or issue tracker.Speedcrunch can perform calculations with up to 50 digits, using complex. The app complies with the inclusion criteria Additionally, Notepad++ has a number of auto-completion features and keyboard.It saves a lot of time simplifying equations for us lazy folk, but the ti - 89 is expensive and slow. The idea for this function was shamelessly stolen from the solve function of the ti - 89. ( This would be an error just like trying to sqrt ( - 1 ) currently throws an error ). The Complex Number Calculator solves complex equations and gives real and imaginary solutions. A scaled down version could return error in all cases where the answer would not be strictly a single numeric result and when a user tries to pass the function an uninitialized variable, until concepts such as complex numbers can be added to speedcrunch. Enter the equation for which you want to find all complex solutions. I saw that even in degree mode, the angle should be entered in radians for polar form to get correct answers. This more complex function may break too many of the conventions of speedcrunch ( returning only a number, using uninitialized variables ). My second year EE class has begun covering impedances and the phasor domain im the last month, and the complex number calculation seems problematic on my TI-84. solve ( x ^ 2 + x + 1 = 3 x ) returns 1 and - 2 solve ( 2 x = 3 y, x ) returns 3 y / 2 ( y is not initialized ) The real difficulty in creating this function would be the different outputs that can come from solving some equations, for instance multiple answers, complex answers, catching when equations cannot be solved, and dealing with uninitialized variables, and including uninitialized variables in the output. This function would accept : a : an equation including variables ( initialized and uninitialized ), functions, and numbers b : a variable to solve the equation for This function would return : either a number, or a mixture of numbers and uninitialized variables Test Case : solve ( 1 = sin ( x ) x ) returns 1. Unlimited Variables Syntax Highlighting Functions with ‘Automagic. Perform calculations with up to 50 digits of precision, using complex numbers, numeral bases, unit conversions, and more. Variables allow you to store your results. I have a suggestion for an enhancement : A solve ( a b ) function should be implemented. SpeedCrunch comes with over 80 built-in mathematical functions.
