The sec of 2pi/3 radians is -2, the same as sec of 2pi/3 radians in degrees. To change 2pi/3 radians to degrees multiply 2pi/3 by 180° / π = 120°. Sec 2pi/3 = sec 120 degrees. What is the principal value of tan 1 tan 2π 3?
| A | B |
|---|---|
| 120 degrees | 2pi/3 radians |
| 135 degrees | 3pi/4 radians |
| 150 degrees | 5pi/6 radians |
| 180 degrees | pi radians |
What is the value of 2pi 3 in degrees?
120°What is the Value of Sin 2pi/3? The value of sin 2pi/3 in decimal is 0.866025403. . .. Sin 2pi/3 can also be expressed using the equivalent of the given angle (2pi/3) in degrees (120°).
How do you solve 2pi 3?
1:182:31Compute sec(2pi/3) by hand with no calculator by using the unit circleYouTubeStart of suggested clipEnd of suggested clipThis is pi over 2. And this is pi. And what i like to do is i like to write pi as a number over 3MoreThis is pi over 2. And this is pi. And what i like to do is i like to write pi as a number over 3 because we have 2 pi over 3. So you can write it as 3 pi over 3.
How many degrees is 2pi?
180 degreesBecause say you have 2pi radians, and as we remember pi=180 degrees, so 2pi = 2(180).16-Sept-2016

Does 2pi equal 360 degrees?
0:101:31why is 2 pi = 360 degrees? - YouTubeYouTubeStart of suggested clipEnd of suggested clipNow I just showed you that it can also write that as 2 pi in terms of radians. So we can concludeMoreNow I just showed you that it can also write that as 2 pi in terms of radians. So we can conclude that if the angle measure in radians is 2 pi and the degree measure is 360.
What is 2pi?
There are 2π radians in a full circle. (So 2π radians should equal 360°. Check it out by multiplying 57.30° by 2π = 6.283. You should get 360° to four significant figures.)
How do you evaluate Tan 2pi 3?
The value of tan 2pi/3 is -1.7320508. . .. Tan 2pi/3 radians in degrees is written as tan ((2π/3) × 180°/π), i.e., tan (120°)....We can use trigonometric identities to represent tan 2pi/3 as,cot(pi/2 - 2pi/3) = cot(-pi/6)-cot(pi/2 + 2pi/3) = -cot 7pi/6.-tan (pi - 2pi/3) = -tan pi/3.
What quadrant does 120 degrees lie?
The angle 120∘ is in the second quadrant, and its related angle is 60∘.
How many radians is 270 degrees in terms of pi?
If 1 degree equals π180 radians, then 270 degrees would equal 270 times π180 radians.18-Mar-2018
What is the ratio of the arc length of a circle subtended by that angle divided by the radius of the
An angle measured in radians is the ratio of the arc length of a circle subtended by that angle, divided by the radius of the circle. There are 2π radians in a full circle. (So 2π radians should equal 360°.
How many degrees is a radian?
A circle has 360 degrees or 2pi radians — going all the way around is 2 * pi * r / r. So a radian is about 360 / (2 * pi) or 57.3 degrees. Moving 1 radian (unit) is a perfectly normal distance to travel. what degree is Pi 2?
