|
11 | * Calculate the sine of a value.
|
12 | *
|
13 | * For matrices, the function is evaluated element wise.
|
14 | *
|
15 | * Syntax:
|
16 | *
|
17 | * math.sin(x)
|
18 | *
|
19 | * Examples:
|
20 | *
|
21 | * math.sin(2) // returns number 0.9092974268256813
|
22 | * math.sin(math.pi / 4) // returns number 0.7071067811865475
|
23 | * math.sin(math.unit(90, 'deg')) // returns number 1
|
24 | * math.sin(math.unit(30, 'deg')) // returns number 0.5
|
25 | *
|
26 | * const angle = 0.2
|
27 | * math.pow(math.sin(angle), 2) + math.pow(math.cos(angle), 2) // returns number ~1
|
28 | *
|
29 | * See also:
|
30 | *
|
31 | * cos, tan
|
32 | *
|
33 | * @param {number | BigNumber | Complex | Unit | Array | Matrix} x Function input
|
34 | * @return {number | BigNumber | Complex | Array | Matrix} Sine of x
