Calculatrice scientifique

Comment utiliser ce calculateur

1. Click the keys or type directly. You can type expressions like 2sin(30)+√16 or (1+5%)^10.
2. Press = or Enter to calculate, and Esc to clear. The result preview updates as you type.
3. Switch between degrees (DEG) and radians (RAD) for trigonometric functions. Inverse trig functions have their own keys; press 2nd to turn sinh, cosh and tanh into their inverses.
4. For roots, √x is the square root, ³√x the cube root, and ʸ√x any root: enter the index first, then ʸ√x and the number (3 ʸ√x 8 = 2). EXP enters powers of ten (3 EXP 5 = 3 × 10⁵), and RND inserts a random number between 0 and 1.
5. Use MS to store a value, M+ and M− to add to or subtract from memory, MR to recall and MC to clear. Ans inserts the last result.

Formule

Expressions follow standard mathematical order of operations: parentheses first, then factorials and percentages, then exponents (evaluated right to left), then unary minus, then multiplication and division, and finally addition and subtraction. Calculations use 40-digit decimal arithmetic, so results like 0.1 + 0.2 are exactly 0.3.

−2² = −(2²) = −4

2^3^2 = 2^(3^2) = 512

2π = 2 × π (implicit multiplication)

Examples

1. sin(30) in degrees = 0.5
2. log(1000) = 3; ln(e) = 1
3. 5! = 120; ³√(−8) = −2; 4 ʸ√x 81 = 3
4. 50% = 0.5, so 200 × 15% = 30
5. 1 ÷ 4 EXP 2 = 1 ÷ 400 = 0.0025
