Hints:

1. You can omit unnecessary multiplication signs (instead of 3*t or t*sin(π*t) just type 3t or tsin(πt))

2. Use ≡ (in the top right corner of = button) to simplify expression

3. Just click on the result to copy it to the clipboard

4. Use = button seldom – result is calculating on the fly

4. Add constants for often used values (you can even save expressions)

FAQ

How can I use functions written in the top right and bottom right corners of the button?

Push the button and slide lightly up or down. Depending on value showed on the button action will occur.

How can I toggle between radians and degrees?

To toggle between different angle units you can either change appropriate option in application settings or use the toggle switch located on the 6 button (current value is lighted with yellow color).

Also you can use deg() and rad() functions and ° operator to convert degrees to radians and vice versa.

Examples:

268° = 4.67748

30.21° = 0.52726

rad(30, 21, 0) = 0.52726

deg(4.67748) = 268

Does C++ support %?

Yes, % function can be found in the top right corner of / button.

Examples:

100 + 50% = 150

100 * 50% = 50

100 + 100 * 50% * 50% = 125

100 + (100 * 50% * (25 + 25)% + 100%) = 150

Note:

100 + (20 + 20)% = 140, but 100+ (20% + 20%) = 124.0

100 + 50% ^ 2 = 2600, but 100 + 50 ^ 2% = 101.08

Does C++ support fractional calculations?

Yes, you can type your fractional expression in the editor and use ≡ (in the top right corner of = button). Also you can use ≡ to simplify expression.

Examples:

2/3 + 5/9 ≡ 11/9

2/9 + 3/123 ≡ 91/369

(6 – t) ^ 3 ≡ 216 – 108t + 18t ^ 2 – t ^ 3

Does C++ support complex calculations?

Yes, just enter complex expression (using i or √(-1) as imaginary number).

Examples:

(2i + 1) ^ = -3 + 4i

e ^ i = 0.5403 + 0.84147i

Can C++ plot graph of the function?

Yes, type expression which contains 1 undefined variable (e.g. cos(t)) and click on the result. In the context menu choose ‘Plot graph’.

Does C++ support matrix calculations?

No, it doesn’t

Why I’ve got 1.76732452452345E-17 instead of 0?

Check the ‘Round result’ preference in application settings – it should be turned on.
