What is the exact value of sin 300?

0.866
The value of sin 300° is equal to the y-coordinate (-0.866). ∴ sin 300° = -0.866.

How do you solve COS 330 degrees?

The value of cos 330 degrees can be calculated by constructing an angle of 330° with the x-axis, and then finding the coordinates of the corresponding point (0.866, -0.5) on the unit circle. The value of cos 330° is equal to the x-coordinate (0.866). ∴ cos 330° = 0.866.

How do you find the value of cos 30?

Cos 30° = √3/2 Therefore, the exact value of cos 30 degrees is written as 0.8660 approx. √3/2 is the value of Cos 30° which is a trigonometric ratio or trigonometric function of a particular angle.

Is Cos 300 positive or negative?

We know that 300∘ is in the fourth quadrant, where cosine is positive. 300∘ has a reference angle of 60∘ , since it is 60∘ away from the x -axis.

How do you solve tan 300?

For tan 300 degrees, the angle 300° lies between 270° and 360° (Fourth Quadrant). Since tangent function is negative in the fourth quadrant, thus tan 300° value = -√3 or -1.7320508. . .

What is the exact value of tan150?

FAQs on Tan 150 Degrees Tan 150 degrees is the value of tangent trigonometric function for an angle equal to 150 degrees. The value of tan 150° is -1/√3 or -0.5774 (approx).

What is the exact value of cos 315 degrees?

0.7071
The value of cos 315° is equal to the x-coordinate (0.7071). ∴ cos 315° = 0.7071.

How do you find the value of cos 120?

The value of cos 120 degrees can be calculated by constructing an angle of 120° with the x-axis, and then finding the coordinates of the corresponding point (-0.5, 0.866) on the unit circle. The value of cos 120° is equal to the x-coordinate (-0.5). ∴ cos 120° = -0.5.

How do you find cot 300?

For cot 300 degrees, the angle 300° lies between 270° and 360° (Fourth Quadrant). Since cotangent function is negative in the fourth quadrant, thus cot 300° value = -(1/√3) or -0.5773502. . .
