Sine, cosine and tangent are the principle trigonometric functions. (Image credit: ... the “sine function” written as sin(x), and the “cosine function” written as cos(x).

Trigonometric identities are powerful tools for simplifying complex equations in math and science. Three core ...

The non-linear function usually used for Sine/Cosine-to-Digital conversion is the arc tangent, which calculates the output angle directly from the conditioned sine and cosine signals (see Figure 2).
