[Free PDF] Trigonometry Table for Class 10, 11 and 12
Trigonometry table is used to find the values of trigonometric ratios for various angles. It is a crucial tool for students in Class 10, 11, and 12, especially for those preparing for board exams and competitive tests. This table includes sine, cosine, tangent, cosecant, secant, and cotangent values for angles from 0° to 90° and 0 to π/2 radians.
Trigonometry Table for Class 10, 11, and 12
| Angle (Degrees) | 0° | 30° | 45° | 60° | 90° |
|---|---|---|---|---|---|
| Angle (Radians) | 0 | π/6 | π/4 | π/3 | π/2 |
| Sine (sin) | 0 | 1/2 | √2/2 | √3/2 | 1 |
| Cosine (cos) | 1 | √3/2 | √2/2 | 1/2 | 0 |
| Tangent (tan) | 0 | 1/√3 | 1 | √3 | ∞ |
| Cosecant (csc) | ∞ | 2 | √2 | 2/√3 | 1 |

Trigonometric Functions Table
| Function | Formula |
|---|---|
| Sine (sin) | sin(θ) = Opposite/Hypotenuse |
| Cosine (cos) | cos(θ) = Adjacent/Hypotenuse |
| Tangent (tan) | tan(θ) = Opposite/Adjacent |
| Cosecant (csc) | csc(θ) = 1/sin(θ) |
| Secant (sec) | sec(θ) = 1/cos(θ) |
| Cotangent (cot) | cot(θ) = 1/tan(θ) |
Trick to Remember Trigonometric Values
Use this trick to remember the values of sine, cosine, and tangent for common angles:
- 0°: sin = 0, cos = 1, tan = 0
- 30°: sin = 1/2, cos = √3/2, tan = 1/√3
- 45°: sin = √2/2, cos = √2/2, tan = 1
- 60°: sin = √3/2, cos = 1/2, tan = √3
- 90°: sin = 1, cos = 0, tan = ∞
Steps to Create a Trigonometry Table
- Identify Angles: List the angles for which you need to find the trigonometric values (e.g., 0°, 30°, 45°, 60°, 90°).
- Calculate Values: Use the definitions of sine, cosine, tangent, cosecant, secant, and cotangent to calculate the values for each angle.
- Organize Data: Create a table format to present the values clearly.
- Include Radians: Optionally, include the equivalent angles in radians for better understanding.
