Cos 2 of pi

WebPut cos ( 2 π 5) = x. Using the formulas cos 2 x = 2 cos 2 x − 1, cos 3 x = 4 cos 3 x − 3 cos x , we have 4 x 3 − 2 x 2 − 3 x + 1 = 0 ⇔ ( x − 1) ( 4 x 2 + 2 x − 1) = 0 . Because cos ( 2 π 5) ≠ 1, we get 4 x 2 + 2 x − 1 = 0. Another way, cos ( 2 π 5) > 0, then cos 2 π 5 = − 1 + 5 2.

WebCos pi/2 can also be expressed using the equivalent of the given angle (pi/2) in degrees (90°). We know, using radian to degree conversion, θ in degrees = θ in radians × (180°/ pi) ⇒ pi/2 radians = pi/2 × (180°/pi) = 90° or 90 degrees ∴ cos pi/2 = cos π/2 = cos (90°) = 0 Explanation: For cos pi/2, the angle pi/2 lies on the positive y-axis.
