What trigonometric functions are available on this calculator?

The calculator includes sin, cos, tan, and their inverse functions (arcsin, arccos, arctan). You can switch between degrees and radians mode. For example, sin(30°) = 0.5, while sin(π/6 radians) = 0.5. Perfect for geometry, physics, and engineering calculations.

How do I calculate logarithms and exponentials?

Use log for base-10 logarithms and ln for natural logarithms (base e). The calculator also supports exponential functions like e^x and 10^x. For example, log(100) = 2, ln(e) = 1, and e^2 ≈ 7.389. These functions are essential for scientific calculations and data analysis.

What mathematical constants can I use?

The calculator includes π (pi ≈ 3.14159) and e (Euler's number ≈ 2.71828). Use π for circle calculations, trigonometry, and wave functions. Use e for exponential growth, compound interest, and natural logarithms. These constants are fundamental in mathematics and science.

How do I calculate powers and roots?

Use x² for squares, x³ for cubes, and x^y for any power. For roots, use √x for square roots, ∛x for cube roots, or x^(1/y) for nth roots. For example, 2³ = 8, √16 = 4, and 8^(1/3) = 2. Essential for algebra, physics, and engineering calculations.

Can I perform statistical calculations?

Yes, the calculator includes factorial (!), permutations (nPr), and combinations (nCr) functions. Calculate probabilities, arrangements, and statistical distributions. For example, 5! = 120, 10P3 = 720, and 10C3 = 120. Useful for probability theory and statistics coursework.

How do I use memory functions effectively?

Use M+ to add to memory, M- to subtract from memory, MR to recall memory, and MC to clear memory. This helps with complex calculations requiring intermediate results. Store constants or partial calculations to avoid re-entering values in multi-step problems.

What is the difference between degrees and radians mode?

Degrees mode: Full circle = 360°, commonly used in everyday applications. Radians mode: Full circle = 2π radians, preferred in advanced mathematics. Most trigonometric identities and calculus formulas assume radian measure. Switch modes based on your problem requirements.

How do I handle order of operations correctly?

The calculator follows PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication/Division (left to right), Addition/Subtraction (left to right). Use parentheses to override default precedence. For example, 2+3×4 = 14, but (2+3)×4 = 20.

Can I convert between different number systems?

The calculator supports decimal, binary, octal, and hexadecimal conversions. Useful for computer science, digital electronics, and programming. For example, decimal 255 equals binary 11111111, octal 377, and hexadecimal FF. Switch between bases using the appropriate mode buttons.

What should I do if I get an error or undefined result?

Common errors include division by zero, square root of negative numbers (in real mode), or domain errors for inverse functions. Check your input values and function domains. For example, arcsin only accepts values between -1 and 1. Use complex mode if working with imaginary numbers.
