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).
Calculate sin 90 degrees and more with our sin degrees calculator – your go-to tool for trigonometric calculations. Try it now!
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
degrees = (radians × 180) / π You can also use ourradians to degrees calculatorfor the conversion. Does sine repeat? The sine function is periodic with a period of 2π radians (or 360° in degrees), meaning its values repeat at regular intervals due to the unit circle’s periodic nat...
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...
