## 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

## 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
