asin(x)
Note: This function is not accessible directly, so we need to import math module and then we need to call this
function using math static object.
Parameters
• x -- This must be a numeric value in the range -1 to 1. If x is greater than 1 then it will generate an error.
Return Value
This method returns arc sine of x, in radians.
Example
The following example shows the usage of asin() method.
#!/usr/bin/python
import math
print "asin(0.64) : ", math.asin(0.64)
print "asin(0) : ", math.asin(0)
print "asin(-1) : ", math.asin(-1)
print "asin(1) : ", math.asin(1)
Let us compile and run the above program, this will produce the following result:
asin(0.64) : 0.694498265627
asin(0) : 0.0
asin(-1) : -1.57079632679
asin(1) : 1.57079632679
atan(x)
Description
The method atan() returns the arc tangent of x, in radians.
Syntax
Following is the syntax for atan() method:
atan(x)
Note: This function is not accessible directly, so we need to import math module and then we need to call this
function using math static object.
Parameters
• x -- This must be a numeric value.
Return Value
This method returns arc tangent of x, in radians.
