Geometry's Role in the Math

The importance of geometry's role in the math curriculum is debated in many high schools and colleges. Some schools offer the course while others have done away with it. Based on what you have learned, do you think geometry is a valuable tool for students to learn? Choose one side of this debate, state your view, support your vi

Converging Subsequence

Theorem: Suppose that a sequence S of real numbers has a subsequence that converges to a real number a. Then S converges to a. I know this is true as an if and only if statement, but I need a counter example to show that just one converging subsequence isn't enough. Here are two sequences I'm considering: {1,-1,1,-1,1,-1..

Connected Annulus

Prove the annulus A={z in (the set)R^2 : r <= |z| <= R} is connected. Is it sufficient to show that the annulus is homomorphic to the circle, and then since circle is connected, so is the annulus ? If so, how do you show it, if not, can you shed light on another method?

Cardinality of R and R^2

How can I show that the cardinality of R and R^2, R=set of Real numbers, is equal. I think by R^2 it is meant R x R, which means an ordered pair, am I right? Is this possible just be showing that the first element in R^2 pair can be matched to R? But this is not necessarily a 'function' by definition, so there are infinite

Determining Velocity of Objects

If an object is given an initial velocity straight upward of v0 feet per second from a height of s0 feet , then its altitude's after 1 second is given by the formula: S= -16t2+ v0t + s0. An arrow is shot straight upward with a velocity of 96 feet per second (ft/sec) from an altitude of 6 feet. For how many seconds is t
