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

4. Fibonacci number

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

Ratings and reviews

I have not used all of the programmable functionality, but I'm happy to see it's available. [Edit] It took me _way_ too long to figure out the blue and red additional functions, etc. can be reached by simply pressing the button longer. This is not a criticism, but a confession. I was unable to find any documentation about how to use the phone screen interface, but it never dawned on me that it worked like every other phone app. 😜

Edit: New version is much worse, not a fan of the new UI, the equals button doesn't work the same, and history is broken. It's been 4 months and this hasn't been fixed... Time to move on :/ I was just looking for a simple calculator with a clean ui and a cursor so I could edit mistakes without deleting everything. This calculator does everything I wanted and so much more! It's an absolutely fantastic app. Way better than every other calculator, even the paid ones.

Calling this a “calculator” undersells it—it’s a frontend for an extremely powerful computer algebra environment. However, it’s still a great calculator for the basics, and because it’s so powerful, it will take you just about anywhere you need to go. The recent UI change is great: it looks better and makes all that functionality easier to work with. I’m looking forward to future improvements.
