WebThe reference angle is the positive acute angle that can represent an angle of any measure. The reference angle must be < 90 ∘ . In radian measure, the reference angle must be < π … WebCos 2pi/3 can also be expressed using the equivalent of the given angle (2pi/3) in degrees (120°). We know, using radian to degree conversion, θ in degrees = θ in radians × (180°/ pi) ⇒ 2pi/3 radians = 2pi/3 × (180°/pi) = 120° or 120 degrees ∴ cos 2pi/3 = cos 2π/3 = cos (120°) = - (1/2) or -0.5 Explanation:

WebThe procedure to use the reference angle calculator is as follows: Step 1: Enter the angle in the input field. Step 2: Now click the button “Calculate Reference Angle” to get the result. Step 3: Finally, the reference angle for the given angle will be displayed in the output field. WebFind the Reference Angle -(2pi)/3. Step 1. Find an angle that is positive, less than , and coterminal with . Tap for more steps... Step 1.1. Add to . Step 1.2. The resulting angle of is … Webconvert to degrees and the angle is 2pi/3 * 180/pi = 2 * 180/3 = 2 * 60 = 120 degrees. 120 degrees is in the second quadrant. the reference angle is 180 - 120 = 60 degrees. that's the equivalent angle in the first quadrant. the trig functions for a 60 degree angle are: sin (60) = sqrt (3)/2 cos (60) = .5 tan (60) = sqrt (3) cot (60) = sqrt (3)/3 flixtor clarksons farm
