Understanding the Scientific Calculator

A scientific calculator is a type of electronic calculator, usually but not always handheld, designed to calculate problems in science, engineering, and mathematics. Unlike a basic calculator, it supports functions such as trigonometry, logarithms, and exponential equations.

Key Functions Explained

• Trigonometry (sin, cos, tan): Used to calculate the ratios of sides in right-angled triangles based on angles.
• Logarithms (log): Helps in solving equations where the unknown is an exponent, common in pH scales and decibel levels.
• Square Root (√): Finds the number that, when multiplied by itself, gives the specified value.
• Exponents (x^y): Raises a base number to the power of another number (e.g., 2 raised to the 3rd power is 8).
• Pi (π): A mathematical constant approximately equal to 3.14159, used in circle-related geometry.

Practical Examples

Example 1: Pythagorean Theorem
If a right triangle has sides a=3 and b=4, find the hypotenuse (c) using √(3² + 4²).
Result: 5

Example 2: Circle Area
Find the area of a circle with a radius of 5 units: π × 5².
Result: 78.539…
