Good day to all the readers! ^_^

This contribution is a suggestion for NCalc+ (Open Source).

Application Source:

What is NCalc+ (Open Source) ?

An open source android application specifically, a calculator which provides the following features:

ALGEBRA

1. Computer science
2. Solving the equation:
3. Solve system equations
4. Graphing
5. Cartesian geometry sand (Viet Nam Education)
6. Unit Conversions
7. Simplify expressions
8. Polynomial factorization.
9. Binomial expansion Newton
10. Matrix: evalute matrix step by step

ANALYTICS

1. Derivative
2. Antiderivative
3. Definite integrals
4. Find the limit of the sequence, function

TRIGONOMETRIC

1. Trigonometric expand: sin(2x) -> 2sin(x)cos(x)
2. Trigonometric reduce: 2sin(x)cos(x) -> sin(2x)
3. Trigonometric to exponent: sinh(x) -> (e^x-e^(-x))/2

DETERMINATION OF STATISTICS

1. Combination
2. Permutation

SOME OTHER FEATURES

1. Prime factors
2. Modulo
3. Catalan number
4. Fibonacci number

The Calculator does not show the steps to solve the equations, system of equations, derivative... but only for the final result.

Example Demonstration:
Enter sin(30°) to calculate sine Degree mode

The computer can work in two modes:

• Decimal mode: 0.12312312323
• Mode fractions: for results with arbitrary precision, for example 9^99999

Suggestion

As the title itself states, my suggestion would be an addition of another unit of conversion for temperature. The another unit of conversion for temperature that is meant on this contribution is the “ RANKINE ”. For an engineering student, it is an inevitable fact that dealing with Mathematics cannot be avoided since it is a part of his journey as an engineering student to encounter such subject. Knowing the fact, dealing with Unit Conversions specifically with Temperatures, is said to be unavoidable too. Since then, as an engineering student, he must know the basic units of temperature namely, Degrees Celsius, Degrees Fahrenheit, Degrees Kelvin and Degrees Newton which is already present on NCalc+ App for android. However, those mentioned units are not just the only units for temperature which means there are other units of temperature existing nowadays. One of these units of temperature is the “ Rankine ”. Thus, this suggestion has been made.

What is a Rankine or Rankine Scale?

Rankine most commonly refers to: - William Rankine (1820–1872), Scottish engineer and physicist - Rankine scale, an absolute-temperature scale related to the Fahrenheit scale, named for Rankine - Rankine cycle, a thermodynamic heat-engine cycle, also named after Rankine - Rankine Lecture, a named lecture delivered annually by an expert in the field of geotechnics.

The Rankine scale is an absolute scale of thermodynamic temperature named after the Glasgow University engineer and physicist William John Macquorn Rankine, who proposed it in 1859.

Suggested Format

---

---

1. Go Settings and select “ Unit Converter ”

2. Find “ Rankine ” on the Unit Conversions

3. Select “ Rankine ” on the Unit Conversions

4. Input any value and find it’s equivalent on “ Rankine ”

Benefits

1. Additional unit of temperature to NCalc+ would be helpful to anyone who are dealing with Mathematics specifically those who are studying the topic of Conversions of Temperature Units to gain extra knowledge on the units of temperature and expand their expertise.
2. Another useful and latest unit of temperature will be added to Unit Converter.
3. NCalc+ Unit Converter will be updated and it will be advantageous to both the developer and application users.
4. It will improve, restructure and make the unit conversions of temperature on NCalc+ more beneficial and efficient especially to engineering students and other Major in Mathematics.
5. Makes it easier and faster to convert units of temperature using NCalc+.
