How to Use the Text Analyzer

Trigonometric Functions

First, ensure you're in the correct mode (degrees or radians) using the DEG/RAD button. Enter your angle value and click the desired function (sin, cos, tan). For example, to calculate sin(45°), click [4] [5] [sin].

Logarithms and Exponentials

Use [log] for base-10 logarithms and [ln] for natural logarithms (base e). For exponentials, enter the base, press [^], then enter the exponent. Example: 2^8 = click [2] [^] [8] [=] to get 256.

Using Parentheses

Use parentheses to control the order of operations. For example, to calculate (5 + 3) × 4, click [(] [5] [+] [3] [)] [×] [4] [=] to get 32.

Common Calculations & Examples

Example 1: Calculate sin(45°)

Problem: Find the sine of 45 degrees

Steps:

  1. Ensure calculator is in degree mode (DEG)
  2. Click: [4] [5]
  3. Click: [sin]
  4. Result: 0.7071
Result: 0.7071

Explanation: The sine of 45° is approximately 0.7071 (or √2/2), a fundamental trigonometric value used in physics and engineering.

Example 2: Calculate log(1000)

Problem: Find the common logarithm of 1000

Steps:

  1. Click: [1] [0] [0] [0]
  2. Click: [log]
  3. Result: 3
Result: 3

Explanation: log(1000) = 3 because 10³ = 1000. Common logarithms are useful for working with orders of magnitude.

Example 3: Calculate 2^10

Problem: Find 2 raised to the power of 10

Steps:

  1. Click: [2] [^] [1] [0] [=]
  2. Result: 1024
Result: 1024

Explanation: 2^10 = 1024, commonly used in computer science (1 kilobyte = 1024 bytes).
