Does there exists a brach of mathematics, if exists, perhaps in computational mathematics, researches the properties of multiple nesting functions where every nested function is somewhat simple, such as piecewise linear function?
2. ### Parity of the class number

Hello Can you please tell me about all the availible methodes for studing the parity of the class number of a given number field? Thank you
3. ### Academic Guidance Taking a class in partial differential equations

I love math, but deep down physics is my true love in this life, but you can't do physics without math so my love for mathematics is definitely up there... I digress... I am wrapping up my undergraduate BS in physics, and getting ready for graduate school. I feel pretty good with basic...
4. ### class number of quadratic fields

Hello, Let $d$ be a positive square free integer for which $d$ we have $h(\mathbb{Q}(\sqrt{-2d})=8$? In particular, if $p\equiv 1 \mod 8$ is a prime, when do we have $h(\mathbb{Q}(\sqrt{-2p})=8$? is there any references to sugggest for me? Thank you
5. ### Multiclass M/M/1 queue which can simultaneously have one customer per class

Suppose there is a queue with exponential service time \frac{1}{\mu} which accepts customers from K classes with poisson distribution and rate \lambda_k but if a customer from any class arrives at the queue and there is already another customer from the same queue either waiting or receiving...
6. ### Math Class Problems

Hi, I'm a freshman who is taking Algebra 2, Geometry and Trig all this year. We are doing Geometry right now. The problem is that I failed the last 3 tests and I am freaking out. I don't want to drop the class but if I continue like this I will be forced to drop it. Please help!! I need help...
7. ### Parity of the class number of cyclotomic extensions

Hello, please Is there any results in the parity of $\mathbb Q(\zeta_{p^m})$ ( and $Q(\zeta_{2^m})$ ), with $p$ is an odd prime and $m$ a positive integer ??? Thank you
8. ### tower of length n of finite number fields of odd class numbers?

Hello Let $n$ be any positive integer. Did anyone before construct a tower of length $n$ of finite number fields of odd class number? Do you have any idea about how to do that?
9. ### Why is my book shows that we cannot find the average of entire class?

In my book, In Averages chapter there is a line which tells us: There are two sections A and B of a class where the average height of section A is 150 cm and that of section B is 160 cm. On the basis of this information alone, we cannot find the average of entire class (of the two sections)...
10. ### Congruence Class Proof

Hi, I have tried the question as attached. I am not sure if I am correct. Your help is greatly appreciated. Thanks in advance!
11. ### Complicate Modulus Algebra and Class of the Rest

...be prepared.... I discover that also my Complicate Modulus Algebra shows some properties looking at the Congruence Class of certain tricks... And Fermat the Last is again a good table of work. Again no limits in going deep...
12. ### Academic Guidance What class should I choose?

For the fall I am currently enrolled in: Vector calculus an intro to Java(Data structures) Linear Optimization I have to add 1 more class. I am choosing between Advance Calc. and Intro to Abstract math and proofs. These are the course descriptions of each. Advance Calc: Calculus of several...
13. ### How derive new class of polynomials?

We have g_n(x_0) which is composition of functions f_i(x_0,x_1,...x_{i-1}), i=1..n where f_i(...) are basic arithmetic operations (add, sub, mul) on x_k and constants. For example: x_1 = 2\cdot x_0*x_0 + x_0+0.567 x_2 = x_0x_1 + x_1 + 0.341 x_3 = 3.2x_2x_2+x_1+x_0 this way is simply to reach...
14. ### Cumulative Frequency - Last Class has no Upper Limit

Hi How do you plot the curve when the last class interval has no upper limit? For example, Age_______________....... 70<a<=80____a>80 Frequency__________...... 5____________2 Cumulative Frequency...... 58___________60 So the penultimate point would be (80,58 ), but what would the final point...
15. ### Academic Guidance Trying to decide math class...

Dear all, I just finished a Chemistry 2 class, and it included exponential rates and decay, simple quadratic formula solving, and chemical rate laws. It used some integrals, and I am trying to find a math class to help. I barely got a B, and want to understand it better cuz I am about to take...
16. ### Finding Effective Annual Rate (Financial Management Class)

This is a Perpetuity question and I'm having a hard time finding the EAR(Effective Annual Rate) It states the following: Interest rate: 6 % compounded semi-annually \$100 payed every three months per year So how would you calculate the EAR in this situation? The amount of cash flows per...
17. ### Passing the class

I got a D on my first math exam, and an F on my second math exam, is there any chance I have of passing the class. I am fine with a C. There is one more exam, and a final. What do I do? I am considering dropping the class.
18. ### Bored in math class proof featuring prime numbers

So while I was scribbling in my college calculus class I was just goofing around playing with the harmonic series. \sum_{n=1}^\infty \frac{1}{n} I had decided to separate everything into parts so that you could represent it like this. Hx = \frac{\sum_{n=1}^\infty \frac{1}{n} -...
19. ### Students taking class, and intersections

Attached is the problem. The teacher had an approach but it didnt seem to work, attachment will be posted in the replies.
20. ### How many boys are in the class?

In a class of 52 students, 16 are science students. If 1/3 of the boys and 1/4 of the girls are science students, how many boys are in the class? Total no of student in class = 52 no of science student = 16 no of non science student = 52 - 16 = 36 1/3 of the boys = science students 1/4...
