What is the exact value of csc degree?
Trigonometry Examples Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. The exact value of csc(60) is 2√3 . Multiply 2√3 by √3√3 .
What is the value sin 120?
√3/2
Therefore, sin 120° = √3/2.
Where can I find sec 120?
The value of sec 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 sec 120° is equal to the reciprocal of the x-coordinate(-0.5). ∴ sec 120° = -2.
How do you find the value of tan 120?
For tan 120 degrees, the angle 120° lies between 90° and 180° (Second Quadrant). Since tangent function is negative in the second quadrant, thus tan 120° value = -√3 or -1.7320508. . . Since the tangent function is a periodic function, we can represent tan 120° as, tan 120 degrees = tan(120° + n × 180°), n ∈ Z.
How do you evaluate sin − 120?
For sin 120 degrees, the angle 120° lies between 90° and 180° (Second Quadrant). Since sine function is positive in the second quadrant, thus sin 120° value = √3/2 or 0.8660254. . . Since the sine function is a periodic function, we can represent sin 120° as, sin 120 degrees = sin(120° + n × 360°), n ∈ Z.
What is value of cos 120 degree?
-½
Value of Cos 120 is -½.
How do you find the trigonometric ratio of 120?
120 degrees
- sin 120° = sin (1 × 90° + 30°) = cos 30° = √3/2.
- cos 120° = cos (1 × 90° + 30°) = – sin 30° = – 1/2.
- tan 120° = tan (1 × 90° + 30°) = – cot 30° = – √3.
- csc 120° = csc (1 × 90° + 30°) = sec 30° = 2/√3.
- sec 120° = sec (1 × 90° + 30°) = – csc 30° = – 2.
- cot 120° = cot (1 × 90° + 30°) = – tan 30° = – 1/√3.
What is the value of cot 120?
-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).
How do you simplify 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.
