1. ### Discrete math study strategy - Tips and advice!

I really like your short final outline design. It helps organize the chaos that is scrambling in my brain. I had no idea these topics were grouped this way. I will definitely tell you if your design resembles my final examination. Thank you for taking the time to help me with a general outline...
2. ### Discrete math study strategy - Tips and advice!

We are allowed a page of notes, so that can help during the exam. We covered: Truth tables Negations Existential and Universal Statements Proof of an existential statement Direct proof of a universal statement Disproof of a universal statement Indirect proof of a universal statement Sequences...
3. ### Discrete math study strategy - Tips and advice!

Hi everyone, I haven't been successful in Discrete Math this semester. I have finished all of the calculus I-III series and I did very well. I want to know if anyone can give me some tips on how to study for my final coming up in a few days. Now, I understand that is a vague question but I am...
4. ### Reflexive, Symmetric, Transitive - Prove related problem

What is (z,w)P(x,y)? my guess would be having to prove that x-y=y-x
5. ### Reflexive, Symmetric, Transitive - Prove related problem

How can I show that they are the same? It seems easy to show they are the same if there are variables in place but how would I show they are the same for all real numbers? btw thanks Mark44 for the help
6. ### Reflexive, Symmetric, Transitive - Prove related problem

Homework Statement Let A=RxR=the set of all ordered pairs (x,y), where x and y are real numbers. Define relation P on A as follows: For all (x,y) and (z,w) in A, (x,y)P(z,w) iff x-y=z-w Homework Equations R is reflexive if, and only if, for all x ∈ A,x R x. R is symmetric if, and only if, for...
7. ### Laws of motion Problem

Thank you for the help!
8. ### Laws of motion Problem

I attached an image of the problem I am currently working on. I am having a hard time understanding when to use cosine or sine when referring to the sum of the forces in the y direction or x direction. I have a general understanding as to where you initially place your coordinate system. If you...
9. ### Mathematics behind Hooke's law

I'm trying to understand the math behind Hooke's law and work done by a spring. I'm really looking for clarity. I am trying to understand why after integrating the equation I get three different results. I understand that each formula is specific to a problem but why does this work...
