Supported Functions
| Function | Description | Example |
|---|---|---|
| +, −, ×, ÷ | Basic arithmetic | 12 × 5 = 60 |
| sin, cos, tan | Trigonometric functions | sin(30°) = 0.5 |
| asin, acos, atan | Inverse trigonometric functions | asin(0.5) = 30° |
| sqrt | Square root | sqrt(16) = 4 |
| abs | Absolute value | abs(-9) = 9 |
| ln | Natural logarithm | ln(2.718) = 1 |
| log | Log base 10 | log(100) = 2 |
| π, e | Constants | π = 3.14159, e = 2.718 |
| x^y | Power | 2^3 = 8 |
Angle Modes – DEG vs RAD
When dealing with trigonometric functions, angle measurement matters. Solvezi’s calculator allows you to switch between Degrees (DEG) and **Radians (RAD):
- Degrees (DEG): Most common in geometry and basic math (360° = full circle).
- Radians (RAD): Preferred in higher mathematics, physics, and engineering (2π rad = full circle).
👉 Example:
- sin(90°) in DEG mode = 1
- sin(π/2) in RAD mode = 1
Memory Functions
Scientific problems often require step-by-step calculations. Solvezi’s calculator supports memory storage:
- MC (Memory Clear): Erases stored memory.
- MR (Memory Recall): Retrieves stored value.
- M+ (Memory Add): Adds current result to memory.
- M- (Memory Subtract): Subtracts current result from memory.
This helps when dealing with long equations or multi-step problems.
Who Can Use a Scientific Calculator?
- Students: For algebra, trigonometry, calculus, physics.
- Engineers: For advanced problem-solving, angle measurements, and formula verification.
- Teachers: For explaining scientific concepts in class.
- Researchers: For quick scientific calculations without software.
- Financial Analysts: For logarithmic and exponential growth calculations.
