Trigonometry is one of the most important branches of mathematics used in engineering, physics, architecture, navigation, and even computer graphics. The relationships between angles and side ratios in triangles help us understand real-world problems involving height, distance, waves, and rotations.
6 Trig Functions Calculator
The 6 Trig Functions Calculator is a fast and reliable online tool that instantly computes all six fundamental trigonometric functions—sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot)—using an input angle in degrees.
Instead of manually calculating formulas or using scientific calculators, this tool provides instant results with high accuracy, making it perfect for students, teachers, and professionals.
What Are the 6 Trigonometric Functions?
Trigonometric functions describe relationships between angles and sides in a right-angled triangle. The six primary functions are:
- sin(θ) – ratio of opposite side to hypotenuse
- cos(θ) – ratio of adjacent side to hypotenuse
- tan(θ) – ratio of opposite side to adjacent side
- csc(θ) – reciprocal of sine
- sec(θ) – reciprocal of cosine
- cot(θ) – reciprocal of tangent
These functions are widely used in geometry, wave analysis, signal processing, physics equations, and 3D modeling.
Core Formulas Used in Trigonometry
The calculator is based on standard trigonometric identities and conversions from degrees to radians.
Angle Conversion Formula
Radians=Degrees×180π
Since most programming functions use radians, the calculator first converts the input angle from degrees to radians.

This tool is designed for speed and accuracy, eliminating the need for manual calculations or memorizing complex formulas.
Example Calculation
Let’s understand how the calculator works with a real example.
Example: Angle = 30°
When you input 30 degrees, the calculator first converts it into radians:
30° × π/180 = π/6
Then it calculates:
- sin(30°) = 0.5
- cos(30°) = 0.8660
- tan(30°) = 0.5774
- csc(30°) = 2
- sec(30°) = 1.1547
- cot(30°) = 1.7321
Special Note on Undefined Values
Some angles produce undefined results:
- tan(90°) is undefined (division by zero)
- sec(90°) is undefined
- cot(0°) is undefined
The calculator handles these cases by showing Infinity, ensuring accurate mathematical behavior.
Trigonometric Values Table (Common Angles)
Below is a helpful reference table for standard angles:
| Angle (°) | sin(θ) | cos(θ) | tan(θ) | csc(θ) | sec(θ) | cot(θ) |
|---|---|---|---|---|---|---|
| 0° | 0 | 1 | 0 | ∞ | 1 | ∞ |
| 30° | 0.5 | 0.8660 | 0.5774 | 2 | 1.1547 | 1.7321 |
| 45° | 0.7071 | 0.7071 | 1 | 1.4142 | 1.4142 | 1 |
| 60° | 0.8660 | 0.5 | 1.7321 | 1.1547 | 2 | 0.5774 |
| 90° | 1 | 0 | ∞ | 1 | ∞ | 0 |
This table is useful for quick reference and exam preparation.
