This article mainly introduces how to use the atan () method of Python to calculate trigonometric functions. It is the basic knowledge for getting started with Python. For more information, see atan () returns the arc tangent of x in radians.
This article mainly introduces the use of the Atan () method of using Python to compute trigonometric functions, which is the basic knowledge of the introduction of Python, and the need of friends can refer to
The Atan () method returns the tangent
Both atan and atan2 are antitangent functions, such as two vertices (x1, y1) and point (x2, y2 ); then the two points form the slope angle calculation method is: floatangleatan (y2-y1) (x2-x1); or floatangleatan2 (y2-y1, x2-x1); atan and atan2
The syntax of a atan function
function function: Returns the inverse tangent value.
The tangent value is equal to the number parameter value because it is an angle. The returned angle value is expressed in radians, and the range is-PI/2 to PI/2.
What is the difference between atan,atan2? This article introduces the use and conditions of ATan2.For tan (θ) = y/ x: θ= ATan (y/ x) The range of θ values is [-PI/2, PI/2]. θ= ATan2 (y, x) The range of theta values is [-pi, PI].
When (x,
Describeatan () returns the arc tangent value of x.GrammarThe following is the syntax for the Atan () method:Import Mathmath.atan (x)Note:atan () is not directly accessible, you need to import the math module, and then call the method through the
We can use the tangent operation to change the angle to the slope. How can we use the slope to convert it to the angle? You can use the arc tangent function of the slope to convert it to the corresponding angle. As there are two functions that can
Atan function: Portal.atan2 function: Portal.Atan and atan2 are all seeking the inverse tangent function, such as: There are two points (x1,y1), and Point (X2,y2);Then the angle calculation method of the slope formed by these two points is:float
