UCLA Olga Radko Endowed Math Circle

2/2/2014 -- Beginners Circle: Vector algebra, Pythagoras theorem, rational and irrational numbers. (Oleg Gleizer)

We will continue our study of the algebra of vectors. To better understand multiplication of vectors by some irrational numbers, we will also recall the Pythagoras theorem and use it compute some lengths. Finally, we will refresh our understanding of rational vs. irrational numbers.
