Circular Cone PRO vs RPN 50g

The best app to calculate all quantities of a circular cone. You must enter some quantities like the radius and a height. The algorithm searches the formulas of the missing quantities, shows them and calculates the results. The length of the decimal place can be changed. The algorithm shows when rounding or wrong values lead to an opposition. Decimals and fractions are supported. The solution is shown step by step. All calculations are stored in the history. The final solution can be shared. [ Contents ] - all important quantities for the circular cone - formulas for all important quantities of a circular cone - infographic to illustrate the topic - search bar to find the desired quantity - history function to save the input - detailed solution - positive numbers, decimals and fractions are supported - no ads! [ Usage ] - there are fields for entering values using a special keyboard - press the check mark button at the bottom right to start the calculation - if values are missing, all fields will be marked orange - if the values are wrong (e.g. negative lengths), the affected field will be highlighted red - if a value is no number, it is highlighted in red - the entries in the history can be deleted or sorted - if you select an entry in the history, it will be automatically loaded for the calculation - the whole history can be deleted by pressing a button - solutions can be shared [ Math conditions ] - each value must be greater than zero - angle α, γ must be less than 90° - angle ζ must be less than 180° - angle Ф must be less than 360°

The HP 50g is the last and most powerful of a legendary line: HP 48S, 48G, 49G, 49g+ and finally the 50g — a quarter century of RPN and RPL calculators that engineers, physicists and mathematicians never really let go of. Discontinued in 2015, it remains the reference, and many consider it the best calculator ever made. RPN 50g brings that machine to your iPhone and iPad — not an imitation, the real thing. The app emulates the calculator's hardware (its 75 MHz ARM processor, 512 KB of RAM, 2 MB of flash, the 131×80 display, the keyboard and the SD card slot) and runs HP's original firmware, so it behaves exactly as the calculator on your desk: every function, every mode, every flag, every quirk, key click included. THE CALCULATOR • An advanced computer algebra system: exact rational and arbitrary-precision integer arithmetic, symbolic simplification, factoring, polynomials, derivatives, integrals, limits, Taylor series, equation and system solving, linear algebra • An advanced scientific calculator: complex numbers, vectors and matrices, statistics and regressions, unit conversions with dimensional analysis, base conversions (BIN/OCT/HEX) and bit operations, numeric solver, financial (TVM) calculations, date and time arithmetic • Graphing: 2D function, polar, parametric, conic, slope field, differential equations, statistics and 3D wireframe/surface plots, with zoom, trace and analysis • The Equation Library with over 300 equations of physics and engineering, with units • RPN with the four-level or unlimited stack, or algebraic entry with the equation writer, at your choice • Programmable in RPL (UserRPL and SysRPL): your programs and libraries run as on the real machine THE APP • Three faces: the black 50g, the blue 50g and the HP 49g+ — the 49g+ is the same machine, running the same firmware • Firmware versions 2.15 (2009, with the 2 MB fix), 2.10 and 2.09 — switch between them, each keeps its own memory • Your calculator's memory stays: close the app, come back later, it is exactly where you left it • SD card: put files in the app's folder in Files and they appear on the calculator's card; what the calculator writes to the card lands in Files. Install libraries as on the real machine • HP's manuals (User's Guide, Advanced User's Reference…) can be downloaded into the app and read next to the calculator; the app remembers your page • Paste: type text from the clipboard onto the calculator • Hardware keyboard support on iPad and iPhone • The beeper, so BEEP and key clicks sound like the calculator • Works fully offline, no account, no ads, no tracking ABOUT THE FIRMWARE The app contains no HP software. On first launch you pick a firmware version and it is downloaded from GitHub, where the app keeps an identical copy of the package published on hpcalc.org, the community archive that has hosted HP's own update packages for decades (each package checked against its known fingerprint); the image is then kept on your device.
