# Calculator N+ - Powerful calculator for Android. 

## Overview
This is a powerful android calculator that contains most of the features needed. The power of the application is through the use of the [Symja library](https://github.com/axkr/symja_android_library). The results are displayed by Latex. This project is an open source project that allows people to study, ad-free application.

## ALGEBRA

	1. Computer science
	2. Solving the equation:
	3. Solve system equations
	4. Graphing
	6. Unit Conversions
	8. Simplify expressions
	9. Polynomial factorization.
	10. Binomial expansion Newton
	11. Matrix

## 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
	5. Pi number

## Note

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