Таблица косинусов
Таблица косинусов — это записанные в таблицу посчитанные значения косинусов углов от 0° до 360°. Используя таблицу косинусов Вы сможете провести расчеты даже если под руками не окажется инженерного калькулятора. Чтобы узнать значение косинуса от нужного Вам угла, достаточно найти его в таблице или вычислить с помощью калькулятора.
Калькулятор — косинус угла
cos(°) = 1

What is the Value of Cos 110 Degrees?
The value of cos 110 degrees in decimal is -0.342020143. . .. Cos 110 degrees can also be expressed using the equivalent of the given angle (110 degrees) in radians (1.91986 . . .)
We know, using degree to radian conversion, θ in radians = θ in degrees × (pi/180°)
⇒ 110 degrees = 110° × (π/180°) rad = 11π/18 or 1.9198 . . .
∴ cos 110° = cos(1.9198) = -0.3420201. . .
Explanation:
For cos 110 degrees, the angle 110° lies between 90° and 180° (Second Quadrant). Since cosine function is negative in the second quadrant, thus cos 110° value = -0.3420201. . .
Since the cosine function is a periodic function, we can represent cos 110° as, cos 110 degrees = cos(110° + n × 360°), n ∈ Z.
⇒ cos 110° = cos 470° = cos 830°, and so on.
Note: Since, cosine is an even function, the value of cos(-110°) = cos(110°).
Methods to Find Value of Cos 110 Degrees
The cosine function is negative in the 2nd quadrant. The value of cos 110° is given as -0.34202. . .. We can find the value of cos 110 degrees by:

- Using Trigonometric Functions
Cos 110 Degrees Using Unit Circle
To find the value of cos 110 degrees using the unit circle:
- Rotate ‘r’ anticlockwise to form 110° angle with the positive x-axis.
- The cos of 110 degrees equals the x-coordinate(-0.342) of the point of intersection (-0.342, 0.9397) of unit circle and r.
Hence the value of cos 110° = x = -0.342 (approx)
