Formula Used in “Trigonometry Calculator”
The Trigonometry Calculator utilizes fundamental formulas that relate the angles and sides of triangles. The primary formula leveraged is the Sine Law and the Cosine Law. These laws are essential for solving various problems in trigonometry.
Sine Law
The Sine Law is expressed as:
[
frac{a}{sin(A)} = frac{b}{sin(B)} = frac{c}{sin(C)}
]
Cosine Law
The Cosine Law is expressed as:
[
c^2 = a^2 + b^2 – 2ab cdot cos(C)
]
Step-by-Step Breakdown of the Formula
Sine Law Variables
- a – length of side opposite angle A
- b – length of side opposite angle B
- c – length of side opposite angle C
- A – angle A (in degrees or radians)
- B – angle B (in degrees or radians)
- C – angle C (in degrees or radians)
Cosine Law Variables
- a – length of one side of the triangle
- b – length of another side of the triangle
- c – length of the side opposite angle C
- C – angle between sides a and b (in degrees or radians)
Example Calculation
Let’s consider a triangle where we know the values of two sides and the angle between them. We will use the Cosine Law to find the length of the third side.
Given:
- Side a = 8
- Side b = 6
- Angle C = 60°
Calculation Steps:
- Convert the angle C to radians if necessary.
- Apply the Cosine Law formula:
c^2 = a^2 + b^2 – 2ab cdot cos(C)
- Substitute the known values into the formula:
c^2 = 8^2 + 6^2 – 2 cdot 8 cdot 6 cdot cos(60°)
- Simplify the equation:
c^2 = 64 + 36 – 2 cdot 8 cdot 6 cdot 0.5
- Calculate the values step by step to retrieve the final result for c.
Results Table
| Input | Value |
|---|---|
| Side a | 8 |
| Side b | 6 |
| Angle C | 60° |
| Computed Side c | c ≈ 7.21 |
Using the above methodology, you can easily solve for unknown lengths and angles in any triangle using the Trigonometry Calculator. For more detailed explorations of the laws and formulas of trigonometry, refer to authoritative sources such as Khan Academy’s Trigonometry Course or Math Is Fun.
