What is a Scientific Calculator?
A scientific calculator is an electronic calculator designed to solve problems in science, engineering, and mathematics. It expands on the capabilities of a basic calculator by offering a wide range of additional functions. These include trigonometric functions (sine, cosine, tangent), logarithms, exponential functions, factorials, and scientific constants like Pi. This online version provides all the standard scientific functions in a convenient, accessible format.
Key Functions Explained
- Trigonometric (sin, cos, tan): Used to calculate angles and ratios in right-angled triangles. Essential for physics and engineering.
- Logarithmic (log, ln): Used to solve equations where the variable is an exponent. The 'log' button is base-10, while 'ln' is the natural log (base e).
- Exponential (xʸ, x², x³): Used to raise a number to a power.
- Factorial (n!): The product of all positive integers up to a given number (e.g., 5! = 5 × 4 × 3 × 2 × 1 = 120).
Frequently Asked Questions
What can a scientific calculator do?
A scientific calculator can perform a wide range of mathematical functions beyond basic arithmetic. This includes trigonometric functions (sin, cos, tan), logarithmic functions (log, ln), exponential functions (x^y), factorials (n!), and constants like Pi (π) and Euler's number (e).
How do you use the sin, cos, and tan functions?
The trigonometric functions sin, cos, and tan are used to find the ratios of the sides of a right-angled triangle. On the calculator, you typically enter the angle (in radians or degrees, depending on the mode) and then press the desired function key. For example, sin(30°) = 0.5.
What is the difference between log and ln?
'log' typically refers to the base-10 logarithm, while 'ln' refers to the natural logarithm, which has a base of Euler's number (e ≈ 2.718). Both are used to solve exponential equations.
