###  Formula for calculating the Tsiolkovsky rocket equation:
#  MaxChangeInVelocity = (EffectiveExhaustVelocity) * NaturalLog(InitialTotalMass)/(FinalTotalMass)
#  math.log(x):  Return the natural logarithm of x (to base e).
#  Example: NaturalLogOfX = math.log(x)

# Enter the EffectiveExhaustVelocity, InitialTotalMass, FinalTotalMass

    # Enter the Final Total Mass
    FinalTotalMass = float(input("Enter the Final Total Mass: ") )
