This will give you ...A calculator to find the exact value of a coterminal angle to a given trigonometric angle. Since there are an infinite number of coterminal angles, this calculator finds the one whose size is between 0 and 360 degrees or between 0 and 2π depending on the unit of the given angle. Use of the coterminal angle calculator 1 - Enter the angle: A reference angle is the acute angle formed between the terminal side of an angle in standard position and the x-axis. It serves as a reference point to determine the exact values of trigonometric functions, such as sine, cosine, and tangent . Reference angles are used to simplify complex calculations and reduce problems to a more manageable form.To get the angle relative to the up vector, going clockwise, pass the arguments to atan2 in the order x,y rather than y,x (which gives a result going anticlockwise from a right-pointing vector). So you need something like this: double dx = b_x - cannon_x; double dy = b_y - cannon_y; double angle_in_degrees = Math.toDegrees (Math.atan2 …

Follow these steps to calculate the reference angle for any given angle: 1. Convert the given angle to degrees: If the provided angle is in radians, convert it to degrees using the conversion factor (180°/π). For instance, if you have an angle of 3π/4 radians, you would calculate: Angle (in degrees) = (3π/4) * (180°/π) = 135°. 2.This calculator is used to add and subtract angles in the form Degrees - Minutes - Seconds (DMS). Each degree is divided into 60 minutes, and each minute further divided into 60 seconds. This form is used in astronomy and defining latitude and longitude. Example 34° 24' 16''. This is read as "34 degrees 24 minutes 16 seconds". Trigonometry. Find the Reference Angle -140. −140 - 140. Find an angle that is positive, less than 360° 360 °, and coterminal with −140° - 140 °.
