How do you find the value of cos 120?
The value of cos 120 degrees can be calculated by constructing an angle of 120° with the x-axis, and then finding the coordinates of the corresponding point (-0.5, 0.866) on the unit circle. The value of cos 120° is equal to the x-coordinate (-0.5). ∴ cos 120° = -0.5.

Why pi radians is 180 degrees?
The value of 180 degrees in radians is π. Because 2π = 360 degrees. When we divide both sides by 2, we get π = 180 degrees.
What is radian formula?
Formula of Radian Firstly, One radian = 180/PI degrees and one degree = PI/180 radians. Therefore, for converting a specific number of degrees in radians, multiply the number of degrees by PI/180 (for example, 90 degrees = 90 x PI/180 radians = PI/2).

What is 120 degree angle called?
obtuse angle An obtuse angle can also be found out if we have the measure of the acute angle. In the picture above, line segment DO intersects line segment OQ at point O and forms an angle DOQ measuring 120°. Thus, it is an obtuse angle.
What is the angle of 120 degree?
obtuse angle-an angle between 90 and 180 degrees.
What is the cot of 120 degrees?
-0.5774 Cot 120 degrees is the value of cotangent trigonometric function for an angle equal to 120 degrees. The value of cot 120° is -(1/√3) or -0.5774 (approx).
What is the value of tan 120 degrees in fraction?
FAQs on Tan 120 Degrees Tan 120 degrees is the value of tangent trigonometric function for an angle equal to 120 degrees. The value of tan 120° is -√3 or -1.7321 (approx).
What quadrant does 120 degrees lie?
second quadrant The angle 120∘ is in the second quadrant, and its related angle is 60∘.
How do you find the exact value of sin 120?
By using the value of cosine function relations, we can easily find the value of sin 120 degrees. Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value. We know that the value of cos 30 degrees is √3/2. Therefore, sin 120° = √3/2.

Is pi 3.14 or 180?
pi=3.14. Conventionally this is in radians. When pi=180°, this is in degrees. Don't confuse the two.
Is π equal to 180?
How is 180 Degrees Equal to Pi? We know that 180° is in degrees and π is in radians. To convert 180 degrees in radians, we just use the conversion formula 360° = 2π. Dividing both sides by 2, we get 180° = π.
Why is one radian 57 degrees?
If we draw two straight lines that cross at the centre of a circle such that the length of the circumference between them (an arc) equals the radius, then the angle between these lines is 1 radian. The angular circumference of a circle is 2π radians, or 360 degrees, so that: 1 radian = 360/2π degrees = 57o 17' 44.8”.
What is meant by 1 radian?
