Why inverse sine function also known as arc sine?
Yes, it is called arcsin.
What is the arc function for trigonometric relationships?
The trigonometric function of an angle gives a certain value The arc trigonometric function of value is simply the angle For example, if sin (30 degrees) = 0.500 then arc sine ( 0.500) = 30 degrees
How do you calculate arc measures?
In degrees because an arc is part of the circumference of a circle which has a total of 360 degrees
How do you calculate a segment of an arc on a circle?
Determine the angle opposite the arc and divide by 360. Multiply that by the radius and double the resulting quotient. Multiply by pi. This is the length of the arc.
Why sin angle equal to angle if the angle is very small?
The sine is almost equal to the angle, in case the angle is expressed in radians. Please make a picture of a circle, put a point on the circle at a small angle (say, 10 degrees or less), then draw the sine (a vertical line from the x-axis up to your point) for a small angle. You will see that the arc of the circle has almost the same length as the vertical line you drew. The arc is the angle; the vertical line is the sine.
