## What is the exact value of sec degrees?

Table of Contents

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.

### How do you find tan 150 without a calculator?

We can find the value of tan(150) by converting it into simple terms. tan(150)=tan(180-30)=-cot(30)=-√3.

**How do you solve sin 150?**

The value of sin 150° is equal to the y-coordinate (0.5). ∴ sin 150° = 0.5.

**What is the reference angle of csc 150?**

30 degrees

cosecant is the reciprocal of sine (csc x = 1/sin x), so we need to know the sin, and then we can find the csc. The reference angle for a 150 degree angle is 30 degrees.

## How do you solve cot 150?

For cot 150 degrees, the angle 150° lies between 90° and 180° (Second Quadrant). Since cotangent function is negative in the second quadrant, thus cot 150° value = -√3 or -1.7320508. . .

### How do you find the reference angle of tan 150?

The easiest way to find the value of is to first convert the measure of the angle from radians to degrees as, Looking at a graph, a 150° angle lies in quadrant II, therefore the reference angle is θ’ = 180° – 150° = 30°.

**What is the trigonometric function of 150 degree?**

Trigonometric Functions of 150° : Its terminal arm (ray OA) intersects the standard unit circle in P (x, y), which lies in the second quadrant. Draw segment PM perpendicular to the X-axis. Then OM = l x l and MP = l y l. Now, ΔOMP is a right-angled triangle in which m∠MOP = 30° and OP = 1.

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

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 find the exact value of csc?

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. The exact value of csc(60) is 2√3 . Multiply 2√3 by √3√3 .

### What is the value of sine at 150?

1/2

FAQs on Sin 150 Degrees Sin 150 degrees is the value of sine trigonometric function for an angle equal to 150 degrees. The value of sin 150° is 1/2 or 0.5.

**What is the reference angle for COS 150?**

30

Both are equal because the reference angle for 150 is equal to 30 for the triangle formed in the unit circle. The reference angle is formed when the perpendicular is dropped from the unit circle to the x-axis, which forms a right triangle.
