Your grades have been submitted to CUNYFirst, and a detailed breakdown of your grades (including your score on the the final exam) has been posted to the GRADES page on the OpenLab. Send me an email if you have forgotten the password.
Happy holidays to all, and the very best of luck in your future work.
Just a heads up – I will be submitting grades by the deadline (12/27), but will likely not be able to get them in earlier as I had planned (unfortunately my family has been sick this week). Once I have submitted grades in CUNYFIRST, I will also post detailed info here on the OpenLab.
This assignment is the final deliverable for your project (worth 10 points). It is an individual, not a group, assignment and should be submitted by email, not on the OpenLab.
The Semester Project consisted of a number of related activities and assignments – before you begin writing, please take a look at the list and click each of the links to remind yourself of all the parts of the project.
Assignment (Due before your final exam – Tuesday, December 20th). SUBMIT BY EMAIL, NOT ON THE OPENLAB. This is your chance to reflect on the Semester Project, and to describe your contributions to the major group activities. Please respond to all of the following.
Part 1 (200 words minimum). Write one or two paragraphs reflecting on the Semester Project, from the initial assignment (“OpenLab #5: Bridges and Walking Tours“) through to the final presentations. You can use the following questions to guide your writing if you wish (or you can respond in whatever way you wish):
What was your overall impression of the project? What did you enjoy the most? Least?
Do you feel that the project enhanced your experience of the class? Was the project related to the course material?
How did you feel during the process? What was the best moment? The worst?
Was the project scaffolded appropriately? Did you need more or different support for any of the assignments? Do you have any suggestions for making the project more effective?
Part 2. Describe your personal contributions to the final two major group assignments, the group paper and the group presentation. Do you think that you were an equal contributor in your group? Be as specific as you can.
Assignment (due Thursday, December 15). Imagine that you are invited to speak on the first day of MAT 2071, to give advice to entering students. Write at least three sentences responding to at least one of the following, describing what you would tell them.
What do you wish that you had been told at the start of this class, to help you succeed?
Choose one topic in the course that is especially challenging. Identify it, and give advice to students trying to master that topic.
What is the most important prior knowledge (not taught in the class) that you need in order to succeed? Why is it important?
Extra Credit. Respond to someone else’s comment. Do you agree? disagree? Have anything to add?
Written work: The following problems are SUGGESTED for practice (they could be on the final!), but will NOT be collected. Sec 12.5 p214: 2, 6
Sec 12.6 p216: 1, 2
Sec 13.1 p222: 1, 4, 5 WeBWorK – none OpenLab – OpenLab #8: Advice for the future, Due Thursday 12/15. Project Reflection – Due before the final exam, Tuesday 12/20.
The review sheet for the final exam has been posted under Classroom Resources / Exam Reviews. I will distribute a hard copy of the review questions in class. As always, let me know in person, by email, or here on the OpenLab if you have any questions.
I found the Video created by Vi Hart is fascinating, beacause it make me feel that factoring is way more interesting than what I knew before. She found the pattern of factoring by drawing the stars. Which is very unlike with the way how other teachers introduce pattren of factoring to their students. I loved the out come of the last few drawings.
This video that created by Vi Hart is about how to explore the mysteries of flexagation., by use strips of paper. I found it if very fascinating, you strip and tape it nicely into a twisty – flody loop. and you can flip the Hexaflexagons again and again.
This Video is called Pi Day is Round, I found this is very interesting beacuse I remember that on the day 3/14/15,My hight school math teacher told our class the today is Pi day, but no one queation that if we round the Pi it wil 3.1416, not 3.1415.
Part 2.(Video One)
I am very glad that I got the chance to watch this videos created by Vi Hart, after I watched these videos I was shocked by Lady who create the videos. They show you many very intersting things that related to math, but you will naver see this things in taxt book or learn them in class. In addition, This Videos also shows that math is related to verything in our daliy life. It also convinced me that Math is not just a course, it is a independent world that has it own system and language. However,I think that I did not understant about her Videos was: what was the reason she speak so quickly in her very videos? I had to watch the video three or four time to get understant the concept of the video.
Part 3.
Many student give up math, because they belive that math class is one of most boring class, and it is also very hard. I have been ask many people about what is you favorite class and wich class you hate the most. I found one thing about math is very interesting, many people see math as thery their favorite calss or the class they hete the most. So I come up a conclution that people who understant the math will love math but people who don’t unserstant the math will think it is a very boring class. So as a math teacher, it is important that you can show your student the side of math that is interesting. But it is not a essey thing do to, beacuse, math is not like other courses, you can tell a intersting story about it or do a fancy expaeriment. I believe that Vi Hart showed us a very good way to teach your student math, just like the Video one.
The question: Let f be a mapping that takes as input a Boolean proposition (no quantifiers) and outputs the same proposition but with all ∧ symbols replaced by ∨. For example: $$ f(x_1 ∧ (x_2 → ¬x_5) = (x_1 ∨ (x_2 → ¬x_5) $$ Prove: Let α be a proposition containing only Boolean connectives ∧,∨. […]
As in the question, is it the case that a predicate calculus with these properties is decidable? n-ary predicates quantifiers finite domain of discourse impredicativity disallowed no function terms If so, is it possible to encode the semantics of this logic in Simply Typed Lambda Calculus ($\lambda\to$)?
If we can prove that $¬Y \implies ¬X,$ then is it always possible to prove that $X \implies Y$ without first proving that $¬Y \implies ¬X$ ? Motivation: when studying analysis, there are some problems/theorems where we must prove $X\implies Y$ and then I try to prove it directly, spend hours stuck without being able […]
On a circle, write all the numbers in ascending order from $1$ to $1000$, clockwise. Starting from $1$, colour in all the numbers in a clockwise direction $k$-th number ($1$, $k + 1$, $2k + 1$, ...). The procedure continues until a number is reached which is already is already coloured. At the end of […]
Question. I have trouble understanding how Patrick Suppes in his "Introduction to logic" derives the important sentence (A2) from another two, (A1) and (CrI). Introduction. He uses criterion I: (Cr1): "Given a set of premises, the rules of logical derivation must permit to infer ONLY those conclusions which logically follow from the premises." He also […]
Has anyone systematically studied how powerful hypercomputation can overcome "incompleteness proof theory"? For example: A deductive system for second-order logic in standard semantics with soundness and completeness, How powerful hypercomputation can correctly decide whether a given sequence of symbols is a proof or not? A deductive system for Infinitary logic with soundness and Barwise completeness, […]
$f\in B_n$ is called linear if $f(x_1,\cdots, x_n)=a_0+a_1x_1+\cdots+a_nx_n$ for suitable coefficients $a_0,\cdots, a_n\in \{0,1\}.$ Here $+$ denotes exclusive disjunction (addition modulo 2) and the not written multiplication is conjunction (i.e. $a_ix_i=x_i$ for $a_i=1$ and $a_ix_i=0$ for $a_i=0$) Show that the above representation of a linear function $f$ is unique. Notation meaning: Here $B_n$ stands for […]
I'm trying to solve the following question: Let $A=\left \{ a_1,..,a_n \right \}$ be a finite set of arbitrary elements and $B_1,...,B_m$ subsets of A. Let $k\leq m$ be a natural number. Write a proposition $\gamma$ in propositional logic, such that $\gamma$ is a tautology if and only if there exist $k$ $B_i$ sets, such […]
On page 40 in Kunens "Set Theory An Introduction to Independence Proofs", we are given the following theorem: Gödel. If $\phi(x)$ is any formula with one free variable, $x$, then there is a sentence $\psi$ such that $$\sf{ZF} \vdash \psi \leftrightarrow \phi(\lceil \psi \rceil)$$ (*): (Should really be \textopencorner and \textcorner here, but this is […]
Negate the statement "He will sink unless he swims". How do we write this statement as an if-then statement ? Once it is written as if-then, then it could be using the formula $\neg (P \implies Q) \equiv P \wedge (\neg Q)$.
