WebThe angle 480°, coterminal to angle 120°, is located in the Second Quadrant (Quadrant II). Since cosine function is negative in the 2nd quadrant, thus cos 480 degrees value = - (1/2) or -0.5. Similarly, cos 480° can also be written as, cos 480 degrees = (480° + n × 360°), n ∈ Z. ⇒ cos 480° = cos 840° = cos 1200°, and so on. Webcsc(210) csc ( 210) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosecant is negative in the third quadrant. −csc(30) - csc ( 30) The exact value of csc(30) csc ( 30) is 2 2. −1⋅2 - 1 ⋅ 2. …

WebSec 30. The value of Sec 30 degrees is equal to 2/√3. In trigonometry, you may have learned about three main primary functions, such as sine, cosine and tangent along with them the other three trigonometric functions, such as secant, cotangent and cosecant. Here, you will find the value of sec 30 degrees along with the other secant degree values. WebExplanation: For cot 120 degrees, the angle 120° lies between 90° and 180° (Second Quadrant ). Since cotangent function is negative in the second quadrant, thus cot 120° value = - (1/√3) or -0.5773502. . . Since the cotangent function is a periodic function, we can represent cot 120° as, cot 120 degrees = cot (120° + n × 180°), n ∈ Z. WebCos 210 Degrees Using Unit Circle. To find the value of cos 210 degrees using the unit circle: Rotate ‘r’ anticlockwise to form 210° angle with the positive x-axis. The cos of 210 degrees equals the x-coordinate (-0.866) of the point of intersection (-0.866, -0.5) of unit circle and r. Hence the value of cos 210° = x = -0.866 (approx) diamond b livestock
