# Output
# The square root of 16 is 4.0
# The logarithm of 16 is 2.772588722239781
# The sine of 16 is -0.2879033166650653
# The cosine of 16 is -0.9576594803233847
# In this example, we imported the math module and used some of its functions to calculate the square root, logarithm, sine, and cosine of a number. The math module provides many mathematical functions that can be used in Python programs.
