Y = asin(X) returns the Inverse Sine (sin -1) of the elements of X in radians. The function accepts both real and complex inputs. For real values of X in the interval [-1, 1], asin(X) returns values in the interval [-π/2, π/2]. For real values of X outside the interval [-1, 1] and for complex values of X, asin(X) returns complex values.

ASIN (x) returns the arcsine of x. The arcsine function is the inverse function of the sine function and calculates the angle for a given sine. X must be in the range [-1..1]. The result is an angle expressed in radians. To convert from radians to degrees, use the DEGREES function. The argument x can be a real number, a complex number, or a matrix.

The Asin function is used to calculate the angle of slope of the line.

函数torch.asin()为PyTorch中的反正弦函数提供支持。它期望输入在[-1，1]范围内，并以弧度形式给出输出。如果输入不在[-1，1]范围内，则返回nan。输入类型为张量，如果输入包含多个元素，则将计算按元素的反正弦值。

2018年5月8日 · I am extremely new to MATLAB (as in just picked it up today) and trying to create basic Position, Velocity, and Acceleration plots. I have this so far: theta = (0:1:pi); beta = asin((h+ b*cos(theta))/d); x = b*cos(theta) + d*cos(beta); plot(radtodeg(theta), x*1000);

The asin (x) function returns the arc sin (inverse sin) of its argument. asin returns its argument in radians or degrees, as selected by set angles.

ASIN(x) Returns the arcsine, or inverse sine, of the given number. The result will be in radians or degrees, depending on the Angles options. With "degrees" selected, asin(1) returns 90.

The math.asin() method returns the arc sine of a number. Note: The parameter passed in math.asin() must lie between -1 to 1. Tip: math.asin(1) will return the value of PI/2, and math.asin(-1) will return the value of -PI/2.
