Formula
Available Functions
This scientific calculator supports: sin, cos, tan (in degrees), log (base 10), ln (natural log), √ (square root), ^ (power), ! (factorial), π and e constants.
Trigonometric Functions
All trig functions use degrees, not radians. For example, sin(90) = 1, cos(0) = 1, tan(45) = 1.
Using the Calculator
Type expressions directly or use the button grid. Use parentheses for grouping. Examples: sin(30) + cos(60), log(1000), 2^10, √(144), 5!.

Frequently Asked Questions
What operations does a scientific calculator support?
It supports trigonometric functions (sin, cos, tan), logarithms (log, ln), exponents, factorials, square roots, and constants like π and e.
What is the difference between log and ln?
log (common logarithm) uses base 10, while ln (natural logarithm) uses base e (≈ 2.718). For example, log(100) = 2 and ln(e²) = 2.
How do I switch between degrees and radians for trigonometry?
Most scientific calculators have a DEG/RAD toggle. Ensure you select the correct mode before computing trig functions — using the wrong mode gives incorrect results.
