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 ∘ )

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.

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 × $\pi)$.

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

Oct 4, 2024 · To find the value of cos (330°) without a calculator, we can use the unit circle and the fact that cosine is a periodic function with a period of 360°. cos (330°) = cos (360° - 30°) Using the unit circle, we know that:

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
