What is sin 330 as a fraction?

What is sin 330 as a fraction?

1/2
Sin 330 degrees is the value of sine trigonometric function for an angle equal to 330 degrees. The value of sin 330° is -(1/2) or -0.5.

What is the value of cos 300 degrees in fraction?

Trigonometric Function Values of Special Angles

What is the reference angle of 330 degrees?

30°
Since 330 is thirty less than 360, and since 360° = 0°, then the angle 330° is thirty degrees below (that is, short of) the positive x-axis, in the fourth quadrant. So its reference angle is 30°.

What is the exact value of cos 300?

0.5
The exact value of cos 300 degrees is 0.5.

How do you find sin 330 without a calculator?

The easiest way to go about doing this (with the least work possible) is to subtract a sin value from 360 degrees (as to not have to switch the trigonometric ratio being used). 360 – 330 = 30, so we are subtracting 30 degrees from 360 to get the sin inverse, 330.

What is the exact value of cos 330?

FAQs on Cos 330 Degrees The value of cos 330° is equal to the x-coordinate (0.866). ∴ cos 330° = 0.866.

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.

Where is 330 degrees on the unit circle?

Explanation: 330° is in the 4th quadrant. Tan values are positive in the 1stand3rd quadrants and negative in the 2ndand4th quadrants.

How do you find the exact value of cos 330?

FAQs on 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.
