Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. The exact value of cos(30) cos (30) is √3 2 3 2. The result can be shown in multiple forms. 0.86602540… 0.86602540 …

Cos 330 degrees is the value of cosine trigonometric function for an angle equal to 330 degrees. Understand methods to find the value of cos 330 degrees with examples and FAQs.

Use our cos (x) calculator to find the cosine of 330 degrees - cos (330 °) - or the cosine of any angle in degrees and in radians.

Write cos (33 0 ∘) as cos (18 0 ∘ + 15 0 ∘) = cos (18 0 ∘ + 15 0 ∘) Use the Angle Sum identity: cos ( s + t ) = cos ( s ) cos ( t ) − sin ( s ) sin ( t ) = cos ( 18 0 ∘ ) cos ( 15 0 ∘ ) − sin ( 18 0 ∘ ) sin ( 15 0 ∘ )

Feb 26, 2017 · The cos of 330 degrees is √(3)/2, the same as cos of 330 degrees in radians. To obtain 330 degrees in radian multiply 330° by $\pi$ / 180° = 11/6 $\pi$. Cos 330degrees = cos (11/6 × $\pi)$.

Calculate cos(330) cos is found using Adjacent/Hypotenuse. Determine quadrant: Since 270 330 360 degrees it is located in Quadrant IV. cos is positive. Determine angle type: 330 > 90°, so it is obtuse. cos(330) = √ 3 /2. Using our unit circle measurements, we look up cos(330)cos(330) = 0.86602540049379Excel Formula: =COS(RADIANS(330 ...

Oct 4, 2024 · To find the value of cos(330°), we can use the fact that 330° is in the fourth quadrant of the unit circle. The reference angle for 330° is calculated as follows: Reference angle = 360° - 330° = 30°.

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. The exact value of cos(30) cos (30) is √3 2 3 2. The result can be shown in multiple forms. 0.86602540… 0.86602540 …

Find cos (-330) Explanation: On the trig unit circle: cos (-330) = cos (30 - 360) = cos 30 Trig table gives -> \displaystyle{\cos{{30}}}=\frac{{\sqrt{{3}}}}{{2}} \displaystyle{\cos{{\left(-{330}\right)}}}=\frac{{\sqrt{{3}}}}{{2}}
