Sine function

### EtymologyEdit

From Latin sinus, originally by mistranslation of Arabic جب (jubb). Ultimately from Sanskrit.

### NounEdit

sine (plural sines)

1. (trigonometry, mathematics) In a right triangle, the ratio of the length of the side opposite an angle to the length of the hypotenuse.

#### Usage notesEdit

In various branches of mathematics, the sine of an angle is determined in various ways, including the following:

• The y-coordinate of the point on the unit circle at the given anticlockwise angle from the x-axis.
• The sum of the real or complex power series

$\sum_{n=1}^\infty{{(-1)^{n-1}}\over{(2n-1)!}}x^{2n-1} = x - {1\over 6} x^3 + {1\over 120} x^5 - {1\over 5040} x^7 + ...$
