The cos of 510 degrees is -0.86603, the same as cos of 510 degrees in radians. To obtain 510 degrees in radian multiply 510° by $\pi$ / 180° = 17/6 $\pi$. Cos 510degrees = cos (17/6 × $\pi)$.

Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history ...

To evaluate cos 510 degrees, we can start by recognizing that 510 degrees is greater than 360 degrees, which corresponds to one full circle. In trigonometry, we use the concept of reference angles to evaluate trigonometric ratios for angles greater than 360 degrees.

Nov 22, 2020 · Find the value of cos(510°) Answer:- cos(510°) = - √3/2. Solution:-cos(510°) =cos(360° + 150°) = cos(150°) = cos(180° - 30°) = -cos(30°) = -√3/2. Hence, cos(510°) = -√3/2. Note:- cos(360° + x) =cos(x) cos(180° - x) = -cos(x)

LHS = cos 510° cos 330° + sin 390° cos 120° = cos(360° + 150°) cos(360° – 30°) + sin(360° + 30°) × cos(180° – 60°) = cos 150° cos 30° + sin 30° (-cos 60°)
