What is Scientific Calculator?
A scientific calculator is an advanced calculator designed to perform mathematical operations beyond basic arithmetic. It includes trigonometric functions (sin, cos, tan), logarithms (log, ln), exponents, square roots, and other scientific operations commonly used in mathematics, physics, engineering, and other sciences.
Formula
Trigonometric: sin(x), cos(x), tan(x), sin⁻¹(x), cos⁻¹(x), tan⁻¹(x)
Logarithmic: log₁₀(x), ln(x), eˣ
Powers: x², x³, xʸ, √x, ∛x
Other: n!, |x|, 1/x, π, e
Examples
- sin(30°) = 0.5 - Sine of 30 degrees
- log(100) = 2 - Log base 10 of 100
- ln(e) = 1 - Natural log of e
- √144 = 12 - Square root of 144
- 5! = 120 - Factorial of 5
FAQ
What is the difference between RAD and DEG mode?
RAD (radians) and DEG (degrees) are two different units for measuring angles. In DEG mode, a full circle is 360°. In RAD mode, a full circle is 2π radians. Make sure to select the correct mode based on your input values.
What is the difference between log and ln?
log (common logarithm) uses base 10, while ln (natural logarithm) uses base e (approximately 2.718). For example, log(100) = 2 because 10² = 100, and ln(e) = 1 because e¹ = e.
How do I calculate powers and roots?
Use x² for square, x³ for cube, xʸ for any power, √ for square root, and ∛ for cube root. For example, to calculate 2⁵, enter 2, press xʸ, enter 5, and press =.
