Mathematical formulas and explanations
Trigonometric functions
Sine: sin(θ) = opposite side / hypotenuse
Cosine: cos(θ) = adjacent side / hypotenuse
Tangent: tan(θ) = opposite side / adjacent side
Logarithms
Base 10: log₁₀(x) = y, where 10^y = x
Natural: ln(x) = y, where e^y = x
Base 2: log₂(x) = y, where 2^y = x
Special functions
Square root: √x = y, where y² = x
Cube root: ³√x = y, where y³ = x
Factorial: n! = n × (n-1) × (n-2) × … × 1
Frequently asked questions
What angle units are supported?
The calculator supports three angle units: degrees (°), radians (rad), and gradians (grad). Trigonometric functions operate in the selected unit.
What is the difference between log and ln?
