From my research, the figure related to this image has a circle with a marked sector. The sector's radius is labeled r, and the angle labeled theta. Among the choices, the correct ones are: A. "If the ratio of the arc length to r is 1, then the measure of is 1 radian" and C. "<span>If the measure of is 1 radian, then the arc length is r</span>"
Answer:
B) Sin^-1(-1) = 3pi/2 or 270°
D) Sin^-1(-1) = -pi/2 or -90°
Step-by-step explanation:
Sine function:
The sine function is -1 at 270º(-90º), which is 3pi/2 = -pi/2.
Inverse sine:
The input of the inverse sine function is a value, and the output are the angles which have the sine equal to the input.
Sin^-1(-1)
Angles for which the sine are -1, that is 3pi/2 or 270° and -pi/2 or -90°. Thus, options B and D are correct.
