How to Find the Value of Sin 870 Degrees? The value of sin 870 degrees can be calculated by constructing an angle of 870° with the x-axis, and then finding the coordinates of the corresponding point (-0. Since cosine function is positive in the 1st quadrant, thus cos 780 degrees value = 1/2 or 0. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. = sin 30 ° ∵ sin 180 - θ = sin θ. sin 150 ° = sin 180 ° - 30 °. Since cosine function is negative in the 2nd quadrant, thus cos 480 degrees value = - (1/2) or -0.Trigonometry Find the Exact Value cos (870) cos (870) cos ( 870) Remove full rotations of 360 360 ° until the angle is between 0 0 ° and 360 360 °. See solution. When 870 is divided by 360, the remainder is 150. Electrical Engineering questions and answers. The cos of 127 degrees equals the x-coordinate (-0. In the fourth quadrant, "cos" is positive.0( etanidrooc-y eht ot lauqe si °078 nis fo eulav ehT . . Hence the value of cos 127° = x = -0. Hence, the exact value of cos 150 ° = - 3 2 and sin 150 ° = 1 2. Arithmetic. Hence, all other trigonometric functions are cos 휃 = – ⅗, tan 휃 = 4/3, cot 휃 = ¾, sec 휃 = – 5/3 and cosec 휃 = – 5/4. Hence cos870o =cos(360o ×2+150o) = cos150o Multiples of three degrees are constructible with a straightedge and compass. Decimal Form: −1. Suggest Corrections. Electrical Engineering.Tech from Indian Institute of Technology, Kanpur. Similarly, cos 480° can also be written as, cos 480 degrees = (480° + n × 360°), n ∈ Z.° 063 naht retaerg si ° 078 nevig ehT .detpecca ton era srewsna lamiceD( . A. Given the periodic property of cosine of 150°, to determine the cosine of an angle > 360°, e. tan 7051'44" The angle 480°, coterminal to angle 120°, is located in the Second Quadrant (Quadrant II). Each of sine and cosine is a function of an angle, which is usually expressed in terms of radians or degrees. Matrix. Cos 870 degrees can also be expressed using the equivalent of the given angle (870 degrees) in radians (15. ⇒ cos 480° = cos 840° = cos 1200°, and so on.5. Limits. cos ( 2670 °) = cos ( 2670 - 360 °) Along the same lines, using the aforementioned form, can you look up terms such as cos 150° value, cos 150, cos150° value and what is the cos of 150 degrees, just to name a few..1 Study App and Learning App with Instant Video Solutions for NCERT Class 6, Class 7, Class 8, Class 9, Class 10, Class 11 and Class 12, IIT JEE prep, NEET preparation and CBSE, UP Board, Bihar Board, Rajasthan Board, MP Board, Telangana Board etc Here, the value of cos 870° is equal to -0. Determine the sine, cosine, or tangent functions of the following angels. Differentiation. cos ( 3030 °) = cos ( 3030 - 360 °) Subtracting one integer from another. To find the value of cos 127 degrees using the unit circle: Rotate ‘r’ anticlockwise to form 127° angle with the positive x-axis.) csc ( - 870°)= 0 sec ( - 870°)= 0 cot cos870o =− 23 Explanation: As trigonometric ratios get repeated over a cycle over 2π or 360o .5. Example 2: Evaluate: cos( – 870 o) Solution: cos( – 870 o) = cos(870 o) [as cos ( –휃) = cos 휃 ] = cos ( 2 × 360 o + 150 o) = cos 150 o [as cos (2n휋 + 휃) = cos 휃 ] = cos ( 180 o – 30 o. Often, if the argument is simple enough, the function value will be written without parentheses, as sin θ rather than as sin(θ).
