Analysis is the process of breaking a complex topic or substance into smaller parts in order to gain a better understanding of it. The technique has been applied in the study of mathematics and logic since before Aristotle (384–322 B.C.), though analysis as a formal concept is a relatively recent development.The word comes from the Ancient Greek ἀνάλυσις (analysis, "a breaking-up" or "an untying;" from ana- "up, throughout" and lysis "a loosening"). From it also comes the word's plural, analyses.
As a formal concept, the method has variously been ascribed to Alhazen, René Descartes (Discourse on the Method), and Galileo Galilei. It has also been ascribed to Isaac Newton, in the form of a practical method of physical discovery (which he did not name).
All books in analytical mechanics explain the case of a particle moving on a given static surface. But what happen if, for example, the surface is having some deformation?. I imagine that the principle of virtual work, and hence, D'Alembert are no longer valid since the normal force by the...
First of all, i tried to find w, the angular frequency, by calculating the oscillations from ta to tc, there is ~ 20 oscillations coursed.
so,
w = 2*pi*20/(tc-ta)
ta = 0, tc = 0 + 5.2 ms
And tried to find the factor gama y by A(t) = A*cos(Φ + wt)*e^(-yt/2)
A(0) = 2.75u = A*cos(Φ)
1u = A*cos(Φ...
Hello Everyone!
I want to learn about Fourier series (not Fourier transform), that is approximating a continuous periodic function with something like this ##a_0 \sum_{n=1}^{\infty} (a_n \cos nt + b_n \sin nt)##. I tried some videos and lecture notes that I could find with a google search but...
hi guys i saw this problem in my collage textbook on vector calculus , i don't know if the statement is wrong because it don't make sense to me
so if anyone can help on getting a hint where to start i will appreciate it , basically it says :
$$ \phi =\phi(\lambda x,\lambda y,\lambda...

Following are the two different types of bar-digram that were observed. My questions are:
1. What do bars hanging below 0 mean in the first dig. ?
2. What do bars shooting from -6 mean, also why are they below 0?
3. Like a normal gene (non-ncRNA gene) expression profile...
Hi All,
I am working on this linkage mechanism. Please see the attachment for images. There are 3 pivot points. Two of which are connected to the ground. The" Inside Leg 1" is telescopic to "Leg 2" and has a 120 LB compression gas spring connected at mount points as shown in the image. The leg...
Thank you all for clearing my doubt before. There is a question I want to ask on space and time and this time it is not about the absolute time as I have understood fairly that space and time are always relative.
So Here it is according to GR It is very beautifully explained that Very massive...
I need to find A_v, I want to relate Vin to Vout. To do this I did KVL on the major loop:
$$V_{DD} = I_D*R_D + V_{SD1} - V_{SD2} - I_D*R_D$$
Since M1 = M2 then everything would cancel out and I would just get V_dd = 0 which is probably wrong. This is assuming V_sd1 = V_sd2, is that correct?
Consider this system, above.
If I studied the mechanics of this system, I get this system of equations.
At that point, I choose to study a free vibration problem and drop the damping, and conduct a modal analysis.
I understand the process:vvI assume a solution such that each mass moves...

I consider the band-pass filter of the following configuration (the ##u_m## is a voltage controlled voltage source):
The transfer function is

I've tried to solve the following circuit using mesh equation, but the solution seems to differ from my attempted answer.
Mesh circuit as follows:
My mesh equation is:

and
-10+12(i2)+6s(i2)+2s(i2-i1)=0 (right mesh)
However the answer seems to...
Hi,

Ok, so here is what I have so far:
Suppose ##T_1## is infinite and ##\varphi : T_1 \rightarrow T_2## is a bijection.
Reasoning:
I'm thinking I would then show that there is a bijection, which would be a contradiction since an infinite set couldn't possibly have a one-to-one correspondence...
well each one is a little different so,,,
$$\dfrac{dy}{dt}=\dfrac{ty(4-y)}{3},\qquad y(0) =y_0$$
not sure if this is what they meant on the given expression
As I understand, if you solve the Maxwell's field equations for a resonant cavity, supposing a time dependence of the form ##e^{iwt}##, you get an eigenvalue problem and different modes as possible solutions. I'm reading some notes where the author states that each mode can be associated with a...
