Examples

1. Calculating Sine for Wave Analysis

Physics Student
Background
A student is analyzing a simple harmonic motion problem requiring the sine of a 30-degree angle.
Problem
Need to find the exact sine value to determine the displacement of a pendulum.
How to Use
Input 30 as the angle, select 'degrees' as the mode, and set precision to 4.
Example Config
angle: 30, angleMode: degrees, precision: 4
Outcome
The calculator returns a sine value of 0.5000.

2. Engineering Precision

Mechanical Engineer
Background
An engineer is designing a machine part that requires the tangent of an angle measured in radians.
Problem
Standard calculators often default to degrees, leading to potential errors in CAD software inputs.
How to Use
Input 1.0472 as the angle, select 'radians' as the mode, and set precision to 6.
Example Config
angle: 1.0472, angleMode: radians, precision: 6
Outcome
The calculator provides the tangent value with high precision for accurate component fabrication.
