WebThe arcsine of x is defined as the inverse sine function of x when -1≤x≤1. 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. … WebBy the most commonly accepted definition of arc cosine, for every x\in[-1,1] 0\le\arccos x\le \pi so \sin\arccos x\ge0 Note. Never substitute \pi with 3.14 unless at the last moment ... \sin(2\arccos(x)), please help me understand how to do these kind of problems.
