## Example
The following example demonstrates the use of the asin() method:
#!/usr/bin/python3import 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))
The output of the above example is:
asin(0.64) : 0.694498265626556 asin(0) : 0.0 asin(-1) : -1.5707963267948966 asin(1) : 1.5707963267948966
