【實用教育app】Scientific Expression Calculator|最夯免費app-綠色工廠好玩App

The most versatile scientific calculator for the iPad and no in-app purchases! Now with query variable, Dropbox, and TextExpander support. Expression, RPN & Algebraic modes. The scratchpad for notes, and evaluating equations without the calculator. So many features; d/l the free manual to learn about them before purchase (see link below). Important changes; check the What's New list. New features to come -> watch for updates. If using iOS 7 or later, update to at least 7.1Use the scratchpad to work on problems, create and store equations and notes. Evaluate equations within the scratchpad; Just type two = signs after the equation or use the new gestures, and the scratchpad figures out where the notes end, and the equation begins, adding the solution to your notes. Many, many more functions and constants available in scratchpad equations. The scratchpad text can be synchronized to your Dropbox account.The calculator has many built-in functions, constants and visual memory storage and recall.The Expression mode of the calculator allows you to input an entire equation before evaluation. This is a great advantage whether adding a series of numbers or evaluating a complex trigonometric equation.The RPN or Reverse Polish Notation mode is loved by many calculator users for efficiency. The Algebraic mode is familiar to users, the standard mode on most calculators.The paper tape tracks your input and results, and can be hidden.The Scientific Expression Calculator is a great calculator for students, engineers and scientists. Comments, questions and problems can be sent to "iOS@azarhi.com".Check out the free PDF manual by going to http://www.scicalcapp.com/ and clicking on the download button. The manual is great for learning about all of the features, and the many functions available in the scratchpad.Application advantages: - three modes for solving equations; the unique Expression mode, Algebraic & RPN - a scratchpad for storing notes and solving equations - workflow between scratchpad & calculator - a paper tape for tracking inputs and results with full editing availableApplication features: * A full featured scientific calculator with *• trig functions including hyperbolic• ln, log, log base 2, & log base b functions• power functions, Bessel functions, gamma and Gauss error function• the DMS function for converting decimal number to degrees/minutes & seconds• and many more functions• 10 memories, fully editable• Answer button; track the most recent solution• back arrow button for correcting inputs• 8 often used scientific constants - earth gravity, univ. grav. const, electron mass, electron charge, speed of light, Avogadro's Num, Planck's const, & the ideal gas constant.
