math.atan()

http://www.adilwaseem.com/

Definition
Will return the reverse value of tan().

Syntax
math.atan(x)

Parameters
x=number

Examples
The value is:
 >>> 
>>> import math
>>> math.atan(.0047)
0.004699965392792016
>>> 

operator.itruediv
The operator.itruediv (a,b) is to get the value:
 >>> import operator
>>> import math
>>> operator.itruediv(math.atan(1), math.sin(1))
0.9333633334686526


operator.le(math.asin(),math.atan())
The method returns after dividing the asin() with atan().
 >>> import math
>>> import operator
>>> a=math.asin(.11)
>>> b=math.atan(.91)
>>> operator.le(a,b)
True
>>> operator.__le__(a,b)
True
>>>

The determined that the maximum value of set is not equal to round(.99).
import math
tuple=(math.acos(1),math.asin(.22),math.cos(-1.1), math.atan(.99))
y=max(map(lambda a: a, tuple)).__ne__(round(1.1))
print(y)
>>> 
False
>>>

sum(map())
The function returns with the sum of three tuple.
import math
x=(math.acos(1),math.asin(1),math.atan(1))
y=(math.sin(-1),math.cos(-1),math.tan(-1))
z=(math.cosh(.1),math.sinh(.1),math.tanh(.1))
print("The sum is", sum(map(lambda a,b,c: a+b+c, x,y,z)))
>>>
The sum is 1.7024569992982896
>>>

The method used the math values to generate random using operator.truediv()
import operator
import random
import math

a=math.acos(.65)
b=math.asin(.45)
c=math.atan(1)

d=random.betavariate(a,b)
f=random.gauss(b,c)
g=random.gammavariate(c,a)

h=operator.truediv(d,f)
i=operator.truediv(f,g)
j=operator.truediv(g,d)

list=[h,i,j]

l=max(map(lambda x:x, list))

print(l)

>>>
