For this example, we’ll use 28π/9 2. The coterminal angles of an angle can be calculated in degrees and radians. Using the formula above, you can quickly find the positive and negative coterminal angles of any specified angle.

2 X Pi Radians = 360 Degrees.


Contains information and turn counterclockwise rotation from looking for unknown sides of reference angle is reminding you the generated triangle when you might be careful to. The abbreviation for radian is rad, c or r. Also, you can use these particular angles to find the coordinates of the angles.

When The Terminal Side Is In The First Quadrant (Angles From 0° To 90° Or From 0 To Π/2), The Reference Angle Is The Same As The Given Angle.


The angle α in radians is equal to the angle α in degrees times pi constant divided by 180 degrees: So, you can use this formula. Θ ± 360 * n.

A Reference Angle Is Always Positive And Is Less Than \(90^\Text{O}\).


The steps to calculate the reference angle are here: Simple design, easy to use, and free. Central angle = 3 x (180/π) central angle = 3 x (180/3.14) central angle = 3 x 57.325 central angle = 171.9° the central angle abc is 3 rad or 171.9°.

To Compute The Measure (In Radians) Of The Reference Angle For Any Given Angle Theta, Use The Rules In The Following Table.


Check whether the obtained angle is close to 180° or 360° and by how much. Click calculate and your answer is radius = 3.5329. 1° = π/180° = 0.005555556π = 0.01745329252 rad.

Enter Central Angle =63.8 Then Click Calculate And Your Answer Is Arc Length = 4.0087.


Click the radius button, input arc length 5.9 and central angle 1.67. Gives you the radical values for common sine, cosine, and tangent functions. To convert the angle unit from radians to degrees, just multiply the value by (180/π).
