Rewrite using trig identities: cos (18 0 ∘) cos (15 0 ∘) − sin (18 0 ∘) sin (15 0 ∘) cos ( 33 0 ∘ ) Write cos ( 33 0 ∘ ) as cos ( 18 0 ∘ + 15 0 ∘ ) = cos ( 18 0 ∘ + 15 0 ∘ )

$$ cos (330^0) = cos ( 360^0 -30^0 ) = cos ( 360^0) cos (30^0) + sin (360^0 ) sin ( 30^0) $$ The cosine, sine, tangent and secant of $$ 360^0 $$ equal the cosine, sine, tangent and secant of $$0^0 $$ respectively.

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. Special Angle Values

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 …
