How do you find the exact value of cos 11pi 4?
The value of cos 11pi/4 can be calculated by constructing an angle of 11π/4 radians with the x-axis, and then finding the coordinates of the corresponding point (-0.7071, 0.7071) on the unit circle. The value of cos 11pi/4 is equal to the x-coordinate (-0.7071). ∴ cos 11pi/4 = -0.7071.
How do you convert from radians to degrees?
From the latter, we obtain the equation 1 radian = (180π)o . This leads us to the rule to convert radian measure to degree measure. To convert from radians to degrees, multiply the radians by 180°π radians .
What is the reference angle of cos (- pi 6?
Since π6 is 30 degrees on the unit circle, draw a triangle on the where 30 degrees is the reference angle.

What is the value of cos 1125?
0.7071
The value of cos 1125° is equal to the x-coordinate (0.7071). ∴ cos 1125° = 0.7071.
How do you find tangent on the unit circle?
We have an identity tan x = (sin x) / (cos x). So divide the y-coordinate by the x-coordinate of each point on the unit circle to find the corresponding tangent value.
What is csc?
The cosecant ( csc ) (\csc) (csc)
The cosecant is the reciprocal of the sine. It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle.

How do you find the terminal point of an angle on a unit circle?
Terminal Point on the Unit Circle. To find the terminal point on the unit circle, start at (1, 0), measure the angle in degree or radian on the circle (move counter clockwise if the angle is positive and clockwise if the angle is negative.) The coordinate of the endpoint is called the terminal point.

What is the exact value of cos 11pi 12?
-0.9659258.
The value of cos 11pi/12 is -0.9659258. . .. Cos 11pi/12 radians in degrees is written as cos ((11π/12) × 180°/π), i.e., cos (165°).
What is the angle measure of 11pi 4?
I understand perfectly how to find the reference angle for a degree, such as 150 degress = reference angle of 30 degrees, because the 2nd quadrant goes from 90 to 180 degrees, so you simply subtract 150 from 180 to come up with 30. I get that: 11pi/4 = 495 degrees.
