period

1. period find problem

i was looking at shor's algorithm and had a bright idea, square the numbers rather than multiply by a specific base. this idea however doesn't seem to work. for example, the followng code: def gcd(p,q): if p == 0: return q else: return gcd(q%p,p) N= 97*79 per = 1...

3. Period of a function

Hi, What will be the period of the function: f(x)=\left ( \sin x \right )\h^{\circ} Thanks.
4. Sampling period of g(k)

Given the Z transform in the picture , I apply partial fraction and eventually I got this result G(z) = 1 - (35/3)/ (2z-1) + (62/3)/(5z-4) Then I am struck and I am really not sure to how to proceed from here. How do I find the first 3 sampling period for g(k)
5. How to find if a trigonometric function is even, odd or neither and its period, witho

I am asked to find whether the functions are odd, even, neither and their period, if they have one, of the following functions: f(x) = sin(x) + cos(x) and f(x) = sin(x)cos(x). I know that even if f(x) = f(-x) and odd if f(-x) = -f(x) but all those fuzzy functions come up like for f(x) =...
6. Why can't I add the period to find the next two solutions?

Consider tan(2x) = \sqrt3 for 0 \leq x < 2\pi reference angle x = \tan^{-1}(\sqrt{3}) = \frac{\pi}{3} In the given domain 0 \leq x < 2\pi, the positive ratio of tangent is in quadrants I and III. So the two standard position angles in this interval are 2x = \frac{\pi}{3} and \frac{4\pi}{3}...

From Kepler's orbital period equation: T = 2Ï€âˆšr^3/GM does r = 2Ï€/TâˆšGM?

9. Fundamental period of a composite function

Hi all, I am a little bit confused about determining the fundamental period of a function: x(t) = \cos\left({2 \pi t\over \sqrt{5}}\right) + 7\sin\left({3\pi t\over\sqrt{125}}\right ) I solve it as follows: \begin{aligned} & {2\pi \over {{2 \pi t\over \sqrt{5}}}} = \sqrt{5}\\ & {2\pi \over...
10. Conjecture on period Fibonacci number mod 2^k

The period of a Fibonacci number, F_n\pmod{2^k}, is equal to 3 ( 2^{k-1}). For example, the period of F_n\pmod{2^1} is equal to 3(2^0). The period of F_n\pmod{2^2} is equal to 3(2^1). The period of F_n\pmod{2^3} is equal to 3(2^2). I can't wrap my head around why this is so.
11. Trig problem involving period and shift

There exists a graph of sin with the period being equal to \frac{3\pi }{2}. Given the general equation h(x) = sin(px + q), find all possible values of p and q. If anyone can solve this, I encourage them to show me how step-by-step, as I am not exactly sure how to solve it.
12. Sum of Sin and Cos with equal period

My teacher says that something like a*\sin(b*x)+c*\cos(b*x) can be rewritten as D*\sin(bx+e) if found that D=\sqrt{a^2+b^2} And e? With some trial and error, I found that e is almost equal to (\pi/4) in my example a*\sin(2x)+b*\cos(2x)=\sqrt{a^2+b^2}*\sin(2x+e)
13. Moving from a stable fixed point to a stable period 2 point

I have a question which asks: At which positive value of b does the quadratic 0.5x^2+bx+2.65 move from having a stable fixed point to having a stable period 2 point? How do I go about solving this, and questions similar to it?
14. period difference over changing frequency

Hello...I have joined in the hope that someone can point me at the right approach to this programming problem I have. I'm fairly sure integration/differentiation is the solution, but that is the point at which my mathematical education left me bewildered! I am calculating the frequency of a...
15. Formula for computing accured amount with period deposits

Hi, Does anyone know the formula for computing the accumulated amount of money that a known interest rate, a known number of periods that the interest is compounded, and a known amount of regular deposits that are made during those periods? IN other words, if there are 30 periods, there would...
16. Period and Amplitude for a trig word problem.

I'm not that great at math, but for the most part, I can get by in my Pre-Calc class which is a required part of my core curriculum here at my school. However, I'm having a bit of trouble with this word problem. A pull cord for a lighted ceiling fan is swinging back and forth. The end of the...
17. Allocation of a single value over a period of weeks

I'm a bit over my head here (understatement!) - but have a math problem that I've been searching for an answer for, but haven't been able to solve. I have a single numeric value (dollars) that I need to allocate over a period of weeks. I need to be able to allocate these dollars three ways...
18. Is the period wrong in my equation?

The pedals of an exercise bicycle are mounted on a bracket that is 30cm above the floor. Each pedal is 18cm from the centre of the bracket. A person pedals at 60 rotations/min. Determine a cosine function that models the height of a pedal above the floor h in centimeters as a function of time...
19. Period of sine

Hello! I have to draw a sine between two points in Euclidean space. I can calculate the non-linear distance between them and then I want draw a sine with the specified length. The problem is how can I find period or/and height for this sine? example: height is 4 period is 5/2...
