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 value of x, in radians.
Syntax
The following is the syntax for the Atan () method:
Atan (x)
Note: This function is not directly accessible, so we need to import the math module, and then we need to call this function with the static object of math.
Parameters
X--This must be a numeric value.
return value
This method returns the tangent value of x, in radians.
Example
The following example shows the use of the Atan () method.

Import Math
Print "Atan (0.64):", Math.atan (0.64)
Print "Atan (0):", Math.atan (0)
Print "Atan:", Math.atan (10)
Print "Atan ( -1):", Math.atan (-1)
Print "Atan (1):", Math.atan (1)
When we run the above program, it produces the following results:
