One thing I dislike most about christmas is the shopping and materialism. I'm poor, and never know what to get family members, which seem to change every 3 years. This usually leads to large amounts of stress this time of year and me wasting countless hours online looking for deals when I should...

i got a BST tree each node builded like this: typedef struct node node; struct node { int value; node *left,* right,*next; }; i need to change it into a sorted linked list from the smallest to the biggest. i can't use malloc and i can't change the anything in this tree i...

i got a sorted linked list from the smallest to the biggest in each node i can go 1 , 10 ,100 steps forward i need to find an object in this linked list if the object is found i need to return it if not then null what is the most affective way to do that i can do a simple loop each time it...

I would be glad if someone compiled a list or atleast provide the link for the actions of various oxidizing and reducing agents like LAH, BAH, hydrogen, potassium permanganate etc. and on the various functional groups. This will be very useful to any organic aficionado and I will be very happy...

I have made a list of data from a file, the file contains numbers and I want to calculate with the numbers. How do I make a float of a list where a[1] is: ['0.00500006128645'], I tried to just use float, but then I got: float() argument must be a string or a number

Dear all, List all the functions from the three-element set {1,2,3} to the set {a,b}. The answer I have is 6 functions. However, the answer given at the back of the book has 24 functions: Note: In the following functions, I will use (sub 1) denoting subscript 1. f (sub 1)...

The list of **"Must-Read" Science Books**... Plz suggest Hi all. I am a first semester engineering student in India. I wish to know about the best books there are in science [especially physics]. I am reading Feynman lectures and erwin kreyszig- advanced engineering mathematics right now. The...

Any comment on his list? Items you would reformulate, combine, add or eliminate? Is this checklist a good schematic of the challenges facing theoretical physics at this point in history? I find it helps to have memorized so I can use it as an informal gauge of progress and relevance. One...

Hi all, I've finished a hypothetical problem in which I have determined the optimum damping ratio $\zeta$ for a specific system. This $\zeta$ value (0.265 in my case) minimizes the peak force transmitted through an object. My next step is to take this $\zeta$ value and find some sort of...

Hi Is there a formula which predicts at which temperature a gas condenses to a liquid ?. I think its called the critical temperature. I've found out thay C02 is 31C and Nitrogen -178. If not a formula can someone point me to a list of gases with info. I'd be quite interested to know...

I would like to define and plot a list of functions in Mathematica without typing all them, but I can't find the solution. Let's say that we want to plot x, x^2, ..., x^10 on interval [0,1]. This is what I tried: funclist=Table[#^n&,(n,1,10)] Plot[funclist[x],(x,0,1)] This does...

My son is getting married this weekend and my house happens to be full of women right now. Too much chick talk! The conversation switched to movies, and one of the women mentioned the Great Escape. My response: "Best guy movie ever!" (So it dates me). A second later, Magnificent Seven came up...

Hello! I will now start my process to apply for a physics program in England. I choose England because I want to be better at English and its sounds like a nice country, and USA is way too expensive, what I've heard. The only University I have checked so far is Cambridge, and it didnt sound...

I'm studying for an introductory C++ programming course and I'm trying to write the code for a doubly-circular linked list. To keep it simple, I had written my list to be tailored to that of a wedding dinner guest invitation list. Hence I didn't use templates at all. I've attempted to compile...

i was told to build a method for which if we find the asked value in one of the links we return the previous link i have built a method that supposedly does it the problem is that i was told that this code is wrong because we need to check the "this" link seperatly from the FOR loop why is that...

I've tried to implement a list within a class. I did this so that I can make 2 or more objects, where each object has a list as it's member. Here is the code to it: struct coeffecient { int num; int den; }; struct polynomial { float power; coeffecient coeff; int...

Question: Prove that the list (x^3, sin(x), cos(x)) is linearly independent in V (V being the vector space of real-valued functions. In other words... common everyday math) They're linearly independent, its pretty obvious. The issue is -- proving rigorously. This is not for an assignment, its...
