Scientific Calculator (adfree) v3.5.6

Requirements: 1.6 and up

Overview:  A calculator with 10 computing modes in one application + a handy scientific reference facility

 

CANaRBCgh8XYOvRlwVOhnTzlOd1Ebj_3e3OOQWUD

 

A calculator with 10 computing modes in one application + a handy scientific reference facility - different modes allow: 1) basic arithmetic (both decimals and fractions), 2) scientific calculations, 3) hex, oct & bin format calculations, 4) graphing applications, 5) matrices, 6) complex numbers, 7) quick formulas (including the ability to create custom formulas), 8) quick conversions, 9) solving algebraic equations & 10) time calculations.

Please note that internet permission is needed to allow access to currency exchange rates in the conversion function

Functions include:

 

* General Arithmetic Functions

* Trigonometric Functions - radians, degrees & gradients - including hyperbolic option

* Power & Root Functions

* Log Functions

* Modulus Function

* Random Number Functions

* Permutations (nPr) & Combinations (nCr)

* Highest Common Factor & Lowest Common Multiple

* Statistics Functions - Statistics Summary (returns the count (n), sum, product, sum of squares, minimum, maximum, median, mean, geometric mean, variance, coefficient of variation & standard deviation of a series of numbers), Bessel Functions, Beta Function, Beta Probability Density, Binomial Distribution, Chi-Squared Distribution, Confidence Interval, Digamma Function, Error Function, Exponential Density, Fisher F Density, Gamma Function, Gamma Probability Density, Hypergeometric Distribution, Normal Distribution, Poisson Distribution, Student T-Density & Weibull Distribution

* Conversion Functions - covers all common units for distance, area, volume, weight, density, speed, pressure, energy, power, frequency, magnetic flux density, dynamic viscosity, temperature, heat transfer coefficient, time, angles, data size, fuel efficiency & exchange rates

* Constants - a wide range of inbuilt constants listed in 4 categories:

1) Physical & Astronomical Constants - press to include into a calculation or long press for more information on the constant and its relationship to other constants

2) Periodic Table - a full listing of the periodic table - press to input an element's atomic mass into a calculation or long press for more information on the chosen element - the app also includes a clickable, pictorial representation of the periodic table

3) Solar System - press to input a planet's orbit distance into a calculation or long press for more information on the chosen planet

4) My Constants - a set of personal constants that can be added via the History

* Convert between hex, oct, bin & dec

* AND, OR, XOR, NOT, NAND, NOR & XNOR Functions

* Left Hand & Right Hand Shift

* Plotter with a table also available together with the graph

* Complex numbers in Cartesian, Polar or Euler Identity format

* The main screen of the calculator can also be set to Fractions Mode for general arithmetic functions including use of parentheses, squares, cubes and their roots

* 20 Memory Registers in each of the calculation modes

* A complete record of each calculation is stored in the calculation history, the result of which can be used in future calculations

An extensive help facility is available which also includes some useful scientific reference sections covering names in the metric system, useful mathematical formulas and a detailed listing of physical laws containing a brief description of each law.

A default screen layout is available for each function showing all buttons on one screen or, alternatively, all the functions are also available on a range of scrollable layouts which are more suitable for small screens - output can be set to scroll either vertically (the default) or horizontally as preferred – output font size can be increased or decreased by long pressing the + or - buttons

A full range of settings allow easy customisation - move to SD for 2.2+ users

Please email any questions that are not answered in the help section or any requests for bug fixes, changes or extensions regarding the functions of the calculator - glad to help wherever possible.

      Graphing Calculator by Mathlab PRO v3.1.84
      Requirements: Varies with device
      Overview: Graphing calculator with algebra. Essential tool for school and college. Replaces bulky and expensive handheld graphing calculators.

      Description
      If you're looking for a graphing calculator app that works smoothly and seamlessly, you've found it! Graphing Calculator by Mathlab is a scientific graphing calculator integrated with algebra and is an indispensable mathematical tool for students in elementary school to those in college or graduate school, or just anyone who needs more than what a basic calculator offers. It is designed to replace bulky and costly handheld graphing calculators and works on virtually any Android phone or tablet.
      Furthermore, Graphing Calculator by Mathlab displays calculations as it performs them on the high-quality display of the Android device, making it easier for the user to understand the calculations and see them clearly. This app has two great strengths. First, it acts as a fine scientific calculator, but, more than that, it displays the intermediate steps of the calculations as you type. It allows the students to both watch and learn how the calculations are made and how to find the final answer. Second, the graphing ability is absolutely stunning! Not only does the calculator beautifully display the graphs, but it automatically generates the x- and y- values and displays them as well.

      SleepyTime: Bedtime Calculator PLUS v2.1.7
      Requirements: 2.3+
      Overview: Want to wake up refreshed? Every time you sleep, you enter into a series of sleep cycles that last for around 90 minutes, and waking up during one of the cycles will make you feel groggy and exhausted.
       

       
      Nothing is more important than getting a good night's sleep, and waking up in a good shape let you make the most of your day! SleepyTime is an app designed to help you wake up in-between sleep cycles and allows you to start the day with a clear mind.
      SleepyTime for Android allows you to try and work around this issue.
      The app supports calculating when to wake up, when to go to sleep, and when to wake up if you sleep now. You can then set up an alarm to wake up at the right time. The app is perfect for those with a tight schedule, students, and pretty much anyone who wants to stay in top shape! Skeptical? Try it!
