About this calculator
The Sin Cos Tan Calculator gives you a quick way to work through a calculation. Enter your angle and angle unit; it then returns the result, worked out with the standard method the moment you calculate. It runs fully in the browser, so it is private by design and works offline once loaded.
Made for students and anyone checking their working, it gives the result from your angle and angle unit in one step — clearly laid out, free to use, and computed entirely on your device.
How to use
- Enter the angle to evaluate.
- Choose whether the angle is in degrees or radians.
- Press Calculate to find the ratios.
- Read the sine, cosine, and tangent of the angle.

Inputs are taken exactly as entered, so check for typos before trusting an answer.
Because it runs locally, results appear instantly with no server round-trip.
FAQ
Why is the tangent of 90 degrees not defined?
At 90 degrees the cosine is zero, and dividing by zero is not defined, so the tangent has no finite value there.
Can I enter the angle in radians?
Yes. Switch the unit to radians, and the ratios are calculated directly from the radian value.
What range of angles can I use?
Any angle works, including negative angles and values beyond 360 degrees.
Does the Sin Cos Tan Calculator send my data to a server?
No. The Sin Cos Tan Calculator runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
For a 30° angle: sin 30° = 0.5, cos 30° = 0.866, tan 30° = 0.5774.
