How to Use This Scientific Calculator
- Use number buttons (0-9) and decimal point for basic input
- Select trigonometric functions (sin, cos, tan) for angle calculations
- Use inverse trigonometric functions (sin⁻¹, cos⁻¹, tan⁻¹) for reverse calculations
- Apply logarithmic functions (log, ln) for exponential calculations
- Use memory functions (MC, MR, M+, M-, MS) to store and recall values
- Toggle between DEG (degrees) and RAD (radians) for angle measurements
- Press “=” to calculate results or “C” to clear everything

Frequently Asked Questions
What’s the difference between normal and scientific calculators?
+
Scientific calculators include advanced functions like trigonometric operations, logarithms, exponents, constants (π, e), and memory functions, while basic calculators only handle simple arithmetic.
How to switch between degrees and radians?
+
Use the DEG/RAD toggle buttons above the calculator display. DEG is for degree measurements (0-360), RAD is for radian measurements (0-2π).
Can this calculator be used offline?
+
Yes! This is a client-side calculator that works completely in your browser. No internet connection is required after the page loads.
How do memory functions work?
+
MC clears memory, MR recalls stored value, M+ adds to memory, M- subtracts from memory, and MS stores the current value in memory.
What’s the maximum number this calculator can handle?
+
This calculator uses JavaScript’s number precision, which can handle numbers up to about 1.8×10³⁰⁸ with 15-17 significant digits of precision.
