How do you find the value of tan 150?
For tan 150 degrees, the angle 150° lies between 90° and 180° (Second Quadrant). Since tangent function is negative in the second quadrant, thus tan 150° value = -1/√3 or -0.5773502. . .
Why is sin30 sin 150?
The value of sin 30 degrees and sin 150 degrees are equal. 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.
What is the value of Cosec 150 degree?
2
Cosec 150 degrees is the value of cosecant trigonometric function for an angle equal to 150 degrees. The value of cosec 150° is 2.
How do you find COS 270?
The value of cos 270 degrees can be calculated by constructing an angle of 270° with the x-axis, and then finding the coordinates of the corresponding point (0, -1) on the unit circle. The value of cos 270° is equal to the x-coordinate (0). ∴ cos 270° = 0.
What is the exact value of sec 150?
-2/√3
Sec 150 degrees is the value of secant trigonometric function for an angle equal to 150 degrees. The value of sec 150° is -2/√3 or -1.1547 (approx).
How do you solve 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.
What is the exact value of cot 150?
-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).
What is the reference angle of COS 150?
The value of sin 30 degrees and sin 150 degrees are equal. Both are equal because the reference angle for 150 is equal to 30 for the triangle formed in the unit circle.
