When the sine of y is equal to x: sin y = x. Then the arcsine of x is equal to the inverse sine function of x, which is equal to y: arcsin x = sin-1 (x) = y. See: Arcsin function. Sine table sin(x+y)=sinxcosy+cosxsiny. 具体推导：首先建立直角坐标系，在直角坐标系xOy中作单位圆O，并作出角a,b，与-b，使角a的开边为Ox，交圆O于点P1，终边交圆O于点P2，角b的始边为OP2，终边交圆O于点P3，角-b的始边为OP1，终边交圆O于点P4。 (The notation sin 2 (x) is equivalent to (sin(x)) 2.Warning: sin-1 (x) stands for arcsin(x) not the multiplicative inverse of sin(x).). By observing the graphs of sine and cosine, we can express the sine function in terms of cosine and vice versa: If x and y are the angles of a right angle triangle, then x = y = 45 deg, and sin x = sin y = sin 45 = 0.707.

The same statement, with < replaced by ≤, is a very straightforward consequence of a well-known theorem; simple supplementary considerations then allow ≤ to be improved to <. OK, so | d d x sin. ⁡. ( x) | ≤ 1, so the mean value theorem gives us … In this video, we are going to learn how to derive the identity for sin x - sin y?You can email me at raviranjans@gmail.comOther titles for the video are:Ide Sinus, betecknad sin, är en trigonometrisk funktion.För en enhetsvektor som bildar vinkeln ω med x-axeln i ett tvådimensionellt kartesiskt koordinatsystem anger sin(ω) vektorns y-koordinat.Den var ursprungligen en avbildning av en av de spetsiga vinklarna i en rätvinklig triangel på kvoten mellan motstående katet och triangelns hypotenusa.
