Frequently Asked Questions
What functions does a scientific calculator include?
Our scientific calculator includes trigonometric functions (sin, cos, tan, sin⁻¹, cos⁻¹, tan⁻¹), logarithms (log base 10, natural log ln, exponential eˣ), powers and roots (x², x³, xʸ, √x, ∛x), factorials, absolute value, modulo, constants (π, e), and memory functions (MS, MR, M+, M-, MC).
How do I use radians vs degrees?
Toggle between RAD and DEG modes using the mode button. Radians are used in calculus and physics (360° = 2π radians), while degrees are common in geometry and everyday applications. For trigonometry, use DEG for angles in degrees and RAD for angles in radians.
Does the calculator support keyboard input?
Yes! You can use your keyboard: numbers (0-9), operators (+ - * /), Enter or = for equals, Escape for clear all, Backspace for delete, and decimal point (.). This makes calculations faster and more convenient.
What is the order of operations?
Our calculator follows PEMDAS: Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right). For example, 2 + 3 × 4 = 14 (not 20), because multiplication comes before addition.
How do memory functions work?
Memory functions let you store values: MS (Memory Store) saves the current display, MR (Memory Recall) retrieves stored value, M+ (Memory Add) adds current value to memory, M- (Memory Subtract) subtracts from memory, and MC (Memory Clear) resets memory to 0. Great for complex multi-step calculations.
Can I use this calculator for calculus and physics?
Yes! The calculator supports all essential functions for calculus (trigonometric functions, logarithms, exponentials, powers) and physics calculations. Switch to RAD mode for physics calculations involving angles. Use memory functions to store intermediate results in complex calculations.
What if I get an error?
Errors can occur from invalid operations (e.g., division by zero, square root of negative number, factorial of negative number). Check your input values and ensure they're within valid ranges. Press AC (All Clear) or C (Clear) to reset and try again.
How accurate are the calculations?
Our calculator uses JavaScript's built-in Math functions, which provide high precision (typically 15-17 significant digits). For very large numbers, results are displayed in scientific notation. For most scientific and engineering calculations, this precision is more than sufficient.
