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°.

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.
