What is the exact value of sin 7pi 8?

Sine of seven pi divided by eight. Summary: The exact value of sine of seven pi divided by eight by using a half-angle identity is √2−√22 2 − 2 2 .

What quadrant is 7pi over 3 in?

The angle is in the first quadrant.

Where is 7pi 12 on the unit circle?

Explanation: For sin 7pi/12, the angle 7pi/12 lies between pi/2 and pi (Second Quadrant). Since sine function is positive in the second quadrant, thus sin 7pi/12 value = (√6 + √2)/4 or 0.9659258. . .

Which quadrant is 7pi 12 in?

The angle is in the second quadrant.

What degree is 7 pi?

1260∘
π=180∘ , so 7π=1260∘ .

How do you find 7pi 3 on the unit circle?

7π3=(π3+6π3)=(π3+2π)=π3.

Where is 7pi 2 on the unit circle?

The value of sin 7pi/2 can be calculated by constructing an angle of 7π/2 radians with the x-axis, and then finding the coordinates of the corresponding point (0, -1) on the unit circle. The value of sin 7pi/2 is equal to the y-coordinate (-1). ∴ sin 7pi/2 = -1.

What degree is pi 8?

22.5∘
Thus, π8 radians is equal to 22.5∘. 22.5 ∘ .

What quadrant is 7pi 10 in?

Since the angle 7π10 7 π 10 is in the second quadrant, subtract 7π10 7 π 10 from π .

What is 6pi over 7 in degrees?

In your case, to get the number of radians, just simplify what you have e.g 6⋅π7=18.857 (to 3DP) and so on… So, in your case, we have 6π7 radians, which is the same as 67π . When we figure out which quadrant our angle (154.286°) is in, we can decide which formula to use.

What degree is 7pi 8?

157.5°
Tan 7pi/8 can also be expressed using the equivalent of the given angle (7pi/8) in degrees (157.5°).

How many degrees is 7pi 4 radians?

What is the value of Cot pi by 8?

2.4142
Cot pi/8 is the value of cotangent trigonometric function for an angle equal to π/8 radians. The value of cot pi/8 is 2.4142 (approx).

How many degrees is 6pi?

So, π6 measures 30˚.

What angle is pi over 12?

15 degrees
If you take π12 and multiply it by 180π , you get 15 degrees.

What is a Coterminal angle?

Coterminal angles: are angles in standard position (angles with the initial side on the positive x-axis) that have a common terminal side. For example, the angles 30°, –330° and 390° are all coterminal (see figure 2.1 below).

How many radians are in a circle?

2 radians
The size of a radian is determined by the requirement that there are 2 radians in a circle. Thus 2 radians equals 360 degrees. This means that 1 radian = 180/ degrees, and 1 degree = /180 radians.

What quadrant would degrees be in?

Quadrants & Quadrantal Angles

Angles between 0∘ and 90∘ are in the first quadrant. Angles between 90∘ and 180∘ are in the second quadrant. Angles between 180∘ and 270∘ are in the third quadrant. Angles between 270∘ and 360∘ are in the fourth quadrant.
