-2
The value of Sec 120 degrees is -2. Sec 120 degrees in radians is written as sec (120° × π/180°), i.e., sec (2π/3) or sec (2.094395. . .).
What quadrant does 120 degrees lie?
The angle 120∘ is in the second quadrant, and its related angle is 60∘.
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 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).
How do you solve sec150?

Sec 150 degrees is the value of secant trigonometric function for an angle equal to 150 degrees. The value of sec 150° is -2/√3 or -1.1547 (approx).
What is value of sin180?
The exact value of sin 180 is zero. Sine is one of the primary trigonometric functions which helps in determining the angle or sides of a right-angled triangle. It is also called trigonometric ratio.
What is the reference angle of COS 120?
Cos 120 degree is equal to minus half which can be written as (- ½ ) or (-0.5).
How do you read a quadrant chart?
The first quadrant is the upper right-hand corner of the graph, the section where both x and y are positive. The second quadrant, in the upper left-hand corner, includes negative values of x and positive values of y. The third quadrant, the lower left-hand corner, includes negative values of both x and y.
What is the value of Sec-120°?
⇒ sec 120° = sec 480° = sec 840°, and so on. Note: Since, secant is an even function, the value of sec (-120°) = sec (120°). The secant function is negative in the 2nd quadrant.
How to find the exact value of SEC 60 sec 60?
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because secant is negative in the second quadrant. The exact value of sec(60) sec ( 60) is 2 2. Multiply −1 – 1 by 2 2.
