What is the Sin Cos Tan Calculator?
Calculate sine, cosine, tangent and their reciprocals for any angle. These geometry calculators work out area, perimeter, volume and surface area for common shapes. Units are flexible — enter every length in the same unit and the answer comes back in that unit (squared or cubed).
How to use the Sin Cos Tan Calculator
- Enter your angle, your unit.
- Results update automatically as you type; you can also press Calculate.
- Read the output: sin, cos, tan, csc / sec / cot.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Worked example
With angle = 30, unit = Degrees, the Sin Cos Tan Calculator returns sin: 0.5; cos: 0.866025403784; tan: 0.57735026919.
Tips for better results
- Keep all measurements in one unit before calculating.
- Area units are squared (m², ft²) and volume units are cubed (m³, ft³).
- Use our area and volume converters to switch units afterwards.
