Scientific Calculator

Features of this Scientific Calculator

A scientific calculator goes beyond basic arithmetic to handle complex mathematical, engineering, and scientific computations. This tool is essential for students in algebra, trigonometry, calculus, and physics.

Trigonometric Functions

Calculate angles and lengths in triangles. Note that this calculator uses Degrees for angle inputs by default.

• sin (Sine): Ratio of the opposite side to the hypotenuse.
• cos (Cosine): Ratio of the adjacent side to the hypotenuse.
• tan (Tangent): Ratio of the opposite side to the adjacent side.

Logarithms and Exponents

Essential for solving equations where the unknown variable is an exponent.

• log (Common Logarithm): Logarithm with base 10.
• ln (Natural Logarithm): Logarithm with base e (Euler's number, approx. 2.718).
• ^ (Power): Raises a number to a specific power (e.g., 2^3 = 8).
• √ (Square Root): Finds a number that, when multiplied by itself, equals the input.

Order of Operations

This calculator follows standard mathematical order of operations (PEMDAS/BODMAS):

1. Parentheses first (use "(" and ")" to group terms).
2. Exponents and Roots.
3. Multiplication and Division (left to right).
4. Addition and Subtraction (left to right).

Usage Tips

• To calculate sine of 30 degrees: Click sin, type 30, click ), then =.
• To calculate 5 squared: Type 5, click ^, type 2, then =.
• Use the ⌫ (Backspace) key to correct mistakes without clearing the whole screen.
