WebSine calculator Arcsine definition. The arcsine function is the inverse function of y = sin(x).. arcsin(y) = sin-1 (y) = x + 2kπ For every. k = {...,-2,-1,0,1,2,...}. For example, If the sine of 30° is 0.5: sin(30°) = 0.5. Then the arcsine of 0.5 is 30°:

WebMay 7, 2016 · We can subtract 2π from 19π 6 and still have the same value of cosine--the angles would be in the same location in the unit circle. 19π 6 −2π = 19π 6 − 12π 6 = 7π 6 Thus, cos( 19π 6) = cos(7π 6). Notice that 7π 6 = π + π 6, so this angle is in QIII and has a reference angle of π 6. asia365Web* De Cos: to soon to say if rules need reforming * De Cos: no single culprit for banking turmoil * De Cos: supervisors need to ask "tough questions" By Huw Jones LONDON, April 12 (Reuters) - Board ... asia34WebInverse cosine function. The arccosine of x is defined as the inverse cosine function of x when -1≤x≤1. When the cosine of y is equal to x: cos y = x. Then the arccosine of x is equal to the inverse cosine function of x, which is equal to y: arccos x = cos-1 x = y. Example. arccos 1 = cos-1 1 = 0 rad = 0° See: Arccos function. Cosine table asia 325 ubcWebYou could rearrange the concept a bit to get that the sum of the arguments must be 90 degrees for the sides to be equal, since the sine is the same as the cosine of the complementary angle.
