Volume: 3 dimensions...what?

We are about to study shapes in our world that are 3 dimensional.
My question for you to think about and respond to is this: Look up the formula for finding the volume of a sphere in your book. Look up finding the volume of a n-sided polyhedra. How do you think this formula evolved?
When you answer this, recall the discussion we had about the formula for area of a circle and area of a n-sided polygon.....which took me a few moments to recall for you..
Have a great break!!!

What is Trigonometry? Who is responsible for right triangle trig? Is there one person who is credited for this?

I teach trigonometry in the geometry setting, using right triangles for our basis. But who discovered these relationships? Was there one person who can take the credit? What information is there about this?
Let me know for extra credit!!

Who is this Pythagoras??

After just a little searching, I found out the Pythagoras and his students had a significant impact on our mathematical knowledge!
He was born on Samos, a Greek island in the Aegean Sea that is very close to the west coast of Turkey 580 B.C.
A major belief of his is "All is number". This means that numbers did not just exist as an abstraction or thought in the human mind BUT had a reality all their own that did not depend on one's mind. It meant that numbers and relations between numbers formed the basic core out of which everything else came. "Numbers were to Pythagoreus and his followers what atoms are to the human race today.
Can you find information about Pythagoras and his findings about music??

When I post questions, you may post answers for extra credit!!!

Did you know Pythagoras founded the Order of the Pythagoreans? almost like a religion or cult? Can you tell me more?

What other contributions to mathematics are attributed to Pythagoras and his followers?
