How to Use This Calculator
- Enter the angle in degrees.
- Select the function: sine, cosine, or tangent.
- Click ‘Calculate’.
Formula & Methodology
The calculator uses the following formulas:
- Sine: sin(θ) = opposite/hypotenuse
- Cosine: cos(θ) = adjacent/hypotenuse
- Tangent: tan(θ) = opposite/adjacent
Real-World Examples
Example 1: Bridge Construction
A bridge is 100m long and the angle of inclination is 30°. Calculate the height of the bridge.
Using the calculator, we find the sine of 30° is 0.5. Therefore, the height (h) is 50m.

Interactive FAQ
What is the difference between sine, cosine, and tangent?
Sine, cosine, and tangent are trigonometric functions that relate the sides of a right-angled triangle. Sine is the ratio of the opposite side to the hypotenuse, cosine is the ratio of the adjacent side to the hypotenuse, and tangent is the ratio of the opposite side to the adjacent side.
