An example how logarithms are used to explain a real life occurance? - Answers

not sure exaclty what you asking, but if ur asking for an example of what logarithms are used for in real life, then there are a heaps of examples. briefly, some examples are banks use logarithmic functions to calculate the accumilation of interest in bank accounts over the years (eg. Interest = xyz^0.01k), engineers use it to determine how quick things dry/cool down, etc. if u want a proper algebratic example, here is newtons law of cooling which is: y=yi x e^-kt where: y - different between temprature of body and the constant temp of room yi - initial temprature difference of body and room e - eulers number (2.718...) t - time in mins k - constant for that particular body (usually what u are trying to find out in class tasks) using logarithms, newtons law can predict how how a body (such as cup of coffee) will be after any given period of time. This was the most practicle example i could think of ;) Nick
