The value of arcsin 1 is equal to 90 degrees or π/2 radians. We can find the value of sin inverse 1 using the unit circle and its coordinates which are given by (cos x, sin x).

What is the Value of Sin 27 Degrees in Terms of Cos 27°? Usingtrigonometric identities, we can write sin 27° in terms of cos 27° as, sin(27°) = √(1-cos²(27°)). Here, the value of cos 27° is equal to 0.8910065. ...
This is because sine assumes values between -1 and 1. As for the values assumed by arcsin(x), they fill in the interval in radians [-π/2, π/2] (equal to [-90°, 90°] in degrees). In other words, this interval constitutes the range of sin-1. This is because the sine ...
第一象限是0到3.14/2；第二象限是3.14/2到3.14；第三象限是3.14到3.14*3/2；第四象限是3.14*3/2到3.14*2。看4在那个范围内就在第几象限。这里4在第三象限 望采纳，谢谢
So, the correct answer to what is sin(1) is that sin(1) is approximately 0.841471, when the angle 1 is assumed to be in radians. Now, sin(1) is approximately 0.017452 when 1 is assumed to be expressed in degrees. So then, extreme care should be exercised when dealing with angles. ...
在C语言中，表示正弦值的函数是sin。要使用该函数，首先需要引入数学库，通过以下代码实现：c include 之后，定义一个double类型的变量来存储输入的弧度值。例如，我们希望求取一个角度的正弦值，那么需将角度转换为弧度。c double angle_in_degrees;接着，将角度值转换为弧度。通常，90度等于π/2弧度...
If your argument is in degrees, multiply it by PI()/180 or use the RADIANS function to convert it to radians. Example Copy the example data in the following table and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press ...
