Definition of sine in English: sinenoun sʌɪnsaɪn Mathematics The trigonometric function that is equal to the ratio of the side opposite a given angle (in a right-angled triangle) to the hypotenuse. 〔数〕正弦 Example sentencesExamples - If you use the distance along the ground, you have to find the vertical component by multiplying by the sine of the angle of the hill in both the distance and acceleration terms.
- It presents a one-point iterative technique for calculating the sine of a given angle.
- I can remember roughly how to differentiate a standard xy formula but sines, cosines and tangents are a mystery.
- A mathematical function, like sine or logarithm, gives the same answer to a particular question each time you ask it.
- This same table was reproduced in the work of Brahmagupta and detailed method for constructing a table of sines for any angle were give by Bhaskara in 1150.
OriginLate 16th century: from Latin sinus 'curve', used in medieval Latin as a translation of Arabic jayb 'pocket, sine'. insinuate from early 16th century: This word was first used in legal contexts in the sense ‘enter (a document) on the official register’. Latin insinuare ‘introduce tortuously’ is the source, from in- ‘in’ and sinuare ‘to curve’, from sinus ‘a bend’ found in the sine of mathematics, sinuous, and the sinus (all late 16th century). Nearly all the English senses were already in Latin.
