Logs by the Fire

Logs By The Fire

You've probably seen the "log" button on your calculator, but do you know what it actually does? The resources below will help you to discover how the logarithm function works and how you can use it to solve problems. 

Summing to One 
Age 16 to 18
Challenge Level Yellow star

This problem is a nice introduction that will give you a feeling for how logs work and what that button on your calculator might be doing.

Proving the Laws of Logarithms 
Age 16 to 18
Challenge Level Yellow star

Here you have an opportunity to explore the proofs of the laws of logarithms.

Factorial Fragments 
Age 16 to 18
Challenge Level Yellow starYellow starYellow star

Here you have an expression containing logs and factorials! What can you do with it?

A Big Power 
Age 16 to 18
Challenge Level Yellow star

Have you ever tried to work out the largest number that your calculator can cope with? What about your computer? Perhaps you tried using powers to make really large numbers. In this problem you will think about how much you can do to understand such numbers when your calculator is less than helpful!
