The inverse function of sine function y=sin x on [-π/2, π/2] is called arcsine function. Arcsinx represents an angle with a sine value of x, and the value range of the angle is within the range of [-π/2, π/2]. Domain [- 1, 1], range [-π/2, π/2].
(1) arcsinx is the angle (radian number) on (principal value area).
(2) the sine value of this angle (radian number) is equal to x, that is, sin (arcsinx) = x.
Arcsinx = t/2-arccosx (-1sx-1). Arcsino = 0, arcsin 1=90 .Sinx represents a number, where x is an angle. Arcsinx stands for an angle where x is a number.
Sinx stands for a number, where x is an angle. Arcsinx represents an angle, where x is a number, and arcsinx = t/2-arccosx (-1x ≤1). arcsinO=0，arcsin 1=90 .
ArcsinX refers to the angle whose sine value is x, and ArcsinX is the inverse function of sinx. If sinx=y, then arcsiny=x Because sin is a periodic function, in order to make the function have a unique value, the value range of arcsinx is between (-90,90) degrees. Arcsin0=0, arcsin 1=90 degrees.
