## What is sin of 150 in radians?

0.5

The value of sin 150 degrees is 0.5. Sin 150 degrees in radians is written as sin (150° × π/180°), i.e., sin (5π/6) or sin (2.617993. . .).

**How do you find the value of tan 150 degrees?**

The value of tan 150 degrees in decimal is -0.577350269. . .. Tan 150 degrees can also be expressed using the equivalent of the given angle (150 degrees) in radians (2.61799 . . .) ⇒ 150 degrees = 150° × (π/180°) rad = 5π/6 or 2.6179 . . . ∴ tan 150° = tan(2.6179) = -1/√3 or -0.5773502. . .

**What is the exact value of cot 150 degrees?**

-1.7321

Cot 150 degrees is the value of cotangent trigonometric function for an angle equal to 150 degrees. The value of cot 150° is -√3 or -1.7321 (approx).

### How do you solve COS 150?

Answer: The exact value of cos (150∘) is −√3/2 and sin (150∘) is 1/2.

**How do you find the value of tan?**

As we know, tan is the ratio of sin and cos, such as tan θ = sin θ/cos θ. Thus, we can get the values of tan ratio for the specific angles.

**What is the exact value of csc 150?**

1 Expert Answer Since sin 30 is 1/2, then sin 150 is also 1/2. That means that csc 150 is the reciprocal, which is 2.

## How do you solve Sec 120?

Using trigonometry formulas, we can represent the sec 120 degrees as: ± 1/√(1 – sin²(120°)) ± √(1 + tan²(120°))…We can use trigonometric identities to represent sec 120° as,

- -sec(180° – 120°) = -sec 60°
- -sec(180° + 120°) = -sec 300°
- cosec(90° + 120°) = cosec 210°
- cosec(90° – 120°) = cosec(-30°)

**Is Cos 150 negative?**

Now 150 degrees is in the northwest quadrant of the circle, and -150 degrees is in the southwest quadrant. Each of the lines at these two angles is the same left-right distance from the origin, so cos(150) = cos(-150). Indeed, they are both a negative distance (to the left of the origin).

**Is Cos 150 positive or negative?**

a 150° lies in the second quadrant so cos 150° is negative.
