Hopefully this post isn't too long, I am going to try to give you as much relevant information as possible so you can answer this easily. For a class project, I am required to design a Moore Machine based on a problem that we were given. I have already done this with a Mealy Machine, but I am...

I would do ~(A v B), which simplifies to ~A ^ ~B. But as far as I know A and B are sets so I can't use those symbols.

It's actually the statement x ∈ AUB.

Ok, that makes sense. But I can't use the union symbol, and that's where I'm really confused. Could I say ~(A v B)? ~A ^ ~B by demorgans law.

X is not in A or B? How do I symbolically write that? Because I can't use the union symbol. I initially thought that but it seemed too simple.

Homework Statement Construct the negation of each statement below without using the fol- lowing symbols: ∩, ∪, ⊆, ⊇, ⊂, ⊃, \, △, and =. x ∈ A U B Homework Equations The Attempt at a Solution I don't even know where to start. I'm completely lost. =\

Hi, I'm currently a sophomore at a 4 year university. I'm going to be switching my major to something in engineering. (I've talked to an advisor to verify that I can do this without postponing my graduation. My school offers an undergraduate degree in Computer Systems Engineering and a masters...

Thanks for your response. Why is it necessary to keep going, haven't I already proved C to be true? Nevertheless, here's what I would do next. Because B is true, it follows from statement 2 that D is also true. Because C is true, it follows from statement 3 that E is also true. Then...

Homework Statement Hi, I'm taking a mathematical proofs class and I'm having trouble formatting my proofs correctly. We haven't done any proofs in class yet, but some simple proofs are due in this week's homework assignment. I've tried using the internet to help me, but all the hits that I get...

Thank you. Sometimes when you have a lot on your mind it's easy to forget simple things. :P

Would the limits be: for ρ 0 to 8 for θ 0 to 2pi and for ϕ 0 to pi? If not, I need to review spherical coordinates.

Homework Statement Find the mass of the following object with the given density function: The ball of radius 8 centered at the origin with a density f(ρ,ϕ,θ) = 2e^-p^3 Homework Equations The Attempt at a Solution I know that I need to integrate the density function, but I'm not...

The region from 0 to 3? If that's not right, I guess I'm not visualizing this in the right way. I think I'll graph out the region so I can better see it.

Doesn't it intersect it when z=0? So at y=3?

Homework Statement Find the volume of the solid bounded by the parabolic cylinder y = x^2 and the planes z = 3-y and z = 0Homework Equations The Attempt at a Solution Obviously, a triple integral must be used in the situation. Our professor never explained how to find the limits of...
