- What is the range of cosine values?
- Cosine always returns a value between -1 and 1, regardless of the input angle.
- What is cos(0°) and cos(90°)?
- cos(0°) = 1 and cos(90°) = 0 — cosine starts at its maximum and decreases to zero over the first quarter turn.
- Is this tool free to use?
- Yes — completely free, no account needed. Everything is calculated entirely in your browser and never uploaded to a server.
