Definition of cosine in English:

cosine

noun ˈkəʊsʌɪnˈkoʊˌsaɪn

Mathematics

The trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.
〔数〕余弦
Example sentencesExamples
- Similar questions are investigated for the sine transforms rather than the cosine transforms.
- In fact, it corresponds to the graph of a function called the hyperbolic cosine.
- I can remember roughly how to differentiate a standard xy formula but sines, cosines and tangents are a mystery.
- If the two angles are the same we get the sines and cosines of double the angle.
- The optical path difference is directly proportional to the cosine of the angle of refraction through the coating.
