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!
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...
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 ...
