What is arctan2 in math?​

The quadrant is chosen so that arctan2 (x1, x2) is the signed angle in radians between the ray ending at the origin and passing through the point (1, 0), and the ray ending at the origin and passing through the point (x2, x1). arr2 : [array_like] real valued; x-coordinates.

What is the range of arctan2 in numnumpy?​

NumPy arctan2 range Arctan2 is a 4 quadrant inverse function. That being said, it gives out the value between 0 to 2pi. The range of this function is -180 to 180 degrees.
The numpy.arctan2 () method computes element-wise arc tangent of arr1/arr2 choosing the quadrant correctly. The quadrant is chosen so that arctan2 (x1, x2) is the signed angle in radians between the ray ending at the origin and passing through the point (1, 0), and the ray ending at the origin and passing through the point (x2, x1).
What is the range of the standard arctan function?
In terms of the standard arctan function, whose range is (−π/2, π/2), it can be expressed as follows: The following expression derived from the tangent half-angle formula can also be used to define atan2 :

What is the range of the arctan values?
The range of the angle values is usually between -90° and 90°. There are a number of arctan rules, like that tan (arctan (x)) = x, or that arctanα + arctanβ = arctan ( (α + β) / (1-αβ)), as well as sine of the arctangent: sin (arctan (x)) = x / √ (1+x 2 ), which can help you in trigonometry calculations.

What are the arctan rules for trigonometry?​

There are a number of arctan rules, like that tan(arctan(x)) = x, or that arctanα + arctanβ = arctan((α + β) / (1-αβ)), as well as sine of the arctangent: sin(arctan(x)) = x / √(1+x 2), which can help you in trigonometry calculations.

How do I compute arctan (3/4) and arctangent (4/3)?​

To compute arctan (3/4) or arctan (4/3) or another x/y fraction, simply enter it into the input field and press “calculate”. For convenience, here is a table of common arctangent values of fraction tangents:
