Then the central angle that subtends that arc has a measure of 1 radian. Because C=2πr, there are 2π radians in a full circle. ( 14 votes) neelswapm 7 years ago
WebWe discover that the two radian angles whose cosine is 1/2 are = /3 and = -/3 using the unit circle. We know that both angles have the same reference angle since the reference angle for is 60°, or /3 radians. The two angles are as follows, measured in radians: θ = π/3 and θ = -π/3. The two angles are therefore 3 and -3 in radians. WebIn order to find its reference angle, we first need to find its corresponding angle between 0° and 360°. This is easy to do. We just keep subtracting 360 from it until it’s below 360. For instance, if our angle is 544°, we …

WebOct 10, 2024 · If the angle is in radians, then we do the same rules as for degrees by replacing 180° with π and 360° with 2π. Example: Find the reference angle of 120°. Solution: The given angle is, θ = 120°. We recognize that 120° lies in quadrant II. Applying the above rules, its reference angle is, 180 – θ = 180 – 120 = 60°.
