This article mainly introduces the use of the Cos () method in Python to compute trigonometric functions, which is the basic knowledge of the introduction of Python, the need of friends can refer to the

The Cos () method returns the cosine of x radians.

Grammar

The following is the syntax for the Cos () method:

COS (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 value from 1 to 1, which represents the cosine of the angle

Example

The following example shows the use of the Cos () method

Import Math

print ' cos (3): ", Math.Cos (3)

print ' cos ( -3): ", Math.Cos (-3)

print ' cos (0): ", Math.Cos (0)

print "cos (MATH.PI):", Math.Cos (Math.PI)

print "cos (2*MATH.PI):", Math.Cos (2*MATH.PI)

When we run the above program, it produces the following results:
