    Use cylindrical coordinates to find volume

    Homework Statement Use cylindrical coordinates to find volume... Homework EquationsInside: x2+y2+z2=16 Outside: z=sqrt(x2+y2) The Attempt at a Solution Cylindrical coordinates have always been a problem for me, so I initially tried to put them into spherical and then convert them over, but...

    A little general help (set relation/theory)

    I'm not sure if you read my whole post. I'm not looking for anyone to solve the problem, just some general advice. I was never taught anything about "graphing" sets or relations so the word "graph" is confusing me.

    A little general help (set relation/theory)

    Hey guys! You were all so helpful with a set theory question I had so I was hoping you guys could get me started on something else. Let A = \Gamma x \Gamma where \Gamma represents the set of all real numbers. Thus A is the Cartesian Plane. Consider the collection p defined as follows: p =...

    Set Theory: Proving A-(BUC)=(A\cup B)-C

    Thank you so much! Some research on de morgan is in need! I wish there was a calculator for this stuff. *sigh* For the proof will just showing the calculations work? Or is there a particular way of writing it out I need?

    Set Theory: Proving A-(BUC)=(A\cup B)-C

    Homework Statement [A-(BUC)]U[(A\cup B)-C]U[(A\cap C)-B]U[A\capB\capC]; The Attempt at a Solution Sorry about the crappy formatting (btw). Anyway, I'm trying to "prove" that this is is equal to A. So basically cancelling out the Bs and Cs? I'm not sure how to go about this. de...

    Finding the function to integrate

    Homework Statement Define the function over the four intervals in order to find the area under the curve from [-4,6]. To do so, find the equations of the line and circle, using the data in the graph. Homework Equations None? The Attempt at a Solution To be honest, there...
