How do you tan 270?
Tan 270 degrees can also be expressed using the equivalent of the given angle (270 degrees) in radians (4.71238 . . .) ⇒ 270 degrees = 270° × (π/180°) rad = 3π/2 or 4.7123 . . . Explanation: For tan 270 degrees, the angle 270° lies on the negative y-axis.
How do you find the exact value of 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. . .
How do you solve COS 720?
To find the value of cos 720 degrees using the unit circle, represent 720° in the form (2 × 360°) + 0° [∵ 720°>360°] ∵ cosine is a periodic function, cos 720° = cos 0°.
Which of the following is the value of \cos 180 {\ circ }) cos 180 ∘?
-1
The value of cos 180 is equal to -1.
What does sin 300 degrees equal?
0.866
Sin 300 degrees is the value of sine trigonometric function for an angle equal to 300 degrees. The value of sin 300° is -(√3/2) or -0.866 (approx).
What is the reference angle of COS 300?
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.
What is cos(300∘) = 1 2?
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. Since cos(60∘) = 1 2, we know that cos(300∘) = 1 2 as well since cos(θ) > 0 in the fourth quadrant.
How do you represent the value of cos 60 degrees?
You can represent the value of cos 60 degrees in terms of different angles like 0°, 90°, 180°, 270°. You can also represent it with the help of several other trigonometric sine functions. Consider the unit circle in a cartesian plane as given below.
What is the value of Cos 300 in the fourth quadrant?
300∘ has a reference angle of 60∘, since it is 60∘ away from the x -axis. Since cos(60∘) = 1 2, we know that cos(300∘) = 1 2 as well since cos(θ) > 0 in the fourth quadrant.
What is the value of Cos 150 between 90 and 180?
The cosine function is divided in 4 intervals: if angle is between 0 and 90 it is positive, if between 90 and 180, the angle is negative , for example , cos 150 = – cos 30. In quadrant 180 & 270 , also negative.
