A full rotation?
360 degrees or 2(pi) radians of angle.
Why is 90 degrees taken as angle of reference in trigonometry?
It is not. The angle of reference is 2*pi radians or 360 degrees.
What is the limit of arc tan?
The principal range of arc tan is an angle in the open interval (-pi/2, pi/2) radians = (-90, 90) degrees.
Why does the formula for area of a sector one half r-squared theta not hold true if theta is measured in degrees?
If this is a homework assignment, please consider trying it yourself first, otherwise the value of the reinforcement to the lesson offered by the homework will be lost on you.The area of a circle is pi r2.The area of a sector, defined as the proportion of an angle theta over the angle of a full circle is (pi r2 theta) / (2 pi). That simplifies to (r2 theta) / 2.Using degrees, the same equation is (pi r2 theta) / 360. That does not simplify any further.The reason for this is that theta in radians is defined as the proportion of the circumference of the circle, which is 2 pi r. This makes the math come out easier, which is why most trigonometry is done in radians, not degrees.
What is one fourth of a rotation going counterclockwise?
1/4 of 360 degrees = 90 degrees which is a right angle
What are different kinds of angle differentiate each angle?
Acute angle in the range (0, pi/2) radians = (0, 90) degrees.Right angle = pi/2 radians = 90 degrees.Obtuse angle in the range (pi/2, pi) radians = (90, 180) degrees.Straight angle = pi radians = 180 degrees.Reflex angle in the range (pi, 2*pi) radians = (180, 360) degrees.Full turn = 2*pi radians = 360 degrees.
What kind of angle is 4 pi divided by 5?
pi = 180 degrees pi / 2 = 90 degrees 2 pi = 360 degrees so pi / 5 = 180 / 5 = 36 36 x 4 = 144 degrees a 144 degree angle is obtuse
What is the reference angle for -17pie divided by 6?
-23
What angle is a cube?
The measure of the angle of a cube is pi/2 steradians.
Why straight angle is not reflex angle?
A straight angle is pi radians (180 degrees). A reflex angle is more than pi radian but less than 2*pi radians (between 180 and 360 degrees).
What is 2 pi over 2?
2 pi / 2 = pi.
What is the measure of an angle that is complement of angle M?
pi/2 - M radians
What are the measurements of a right angle?
pi/2 radians.
Is a obtuse angle less or greater than a right angle?
An Obtuse angle is greater than a Right Angle. An Obtuse angle measures more than 90 degrees or pi/2 radians, while a right angle is exactly 90 degrees or pi/2 radians.
Which angle measure less than or equal to 360 is equivalent to an angle of 17π4?
To convert from radians to degrees, multiply by (180 / pi). In this case, if it gives you an angle over 360, subtract 360 repeatedly to get equivalent angles. Or you can repeatedly subtract (2 x pi) from the original angle (in radians), before doing the conversion.
How find radius in a circle given angle and length of arc?
angle of arc/ angle of circle (360°) = length of the arc/ total circumference (2 pi* radius) so you just have to find r then so: angle of arc/ angle of circle (360°) *2pi = length of the arc/ radius radius= ength of the arc/ angle of arc/ angle of circle (360°) *2pi not that hard ;)
What is the reciprocal of pi over two?
(pi/2)-1 = 2/pi
