I was just playing with some numbers and I noticed this weird pattern. Because of the complexity of the problem I am finding it hard to describe it in words. But you can easily understand it by looking at the picture. Whenever I form a series by adding numbers in Arithmetic progression to the...

Hello all, This one thought came to my mind just now. What's the physical significance of signal representation in negative time, i mean second and third quadrant. So for example, sin(t) and sin(t).u(t) aren't they same for all practical purposes? I know, mathematically they are...

Do non periodic signals have frequency? Because my pretty general rule f = 1/T says that they have zero frequency. But suppose i analyze a voice signal. We generally associate a term frequency with them. If you ever had used audacity you might have noticed that the graph is quite...

I am trying to master "AT89C51 datasheet" by understanding it completely. But my limited knowledge is hindering me. help me to overcome all obstacles. It says that Port 0 is an open-drain port. Does it mean that it can only sink current and can't source current? On the next line it says that...

Hi all, I remember my school days when i used to be a very excellent student of my class. I got admission in an engineering institute. I moved to other city for my studies. I rented a room to live in that strange new crowded city. No mom there. I've always been a mamma's boy. With the help...

yes, i have already seen that 5 hours ago. I was silly. i didn't see it on the first place.

Here is my code from my tex file \documentclass[12pt,a4paper]{article} \usepackage[pdftex]{graphicx} \usepackage{amsmath} \usepackage[T1]{fontenc} \usepackage{listings} \lstset{language=C} \newcommand{\HRule}{\rule{\linewidth}{0.5mm}} \begin{document} \input{./title.tex} and here...

If I can do it from some good company then I'd prefer it.

Hi, I am a 4th semester engineering student of electronics and communication discipline. My semester is going to end and I am very worried about the vocational training. I am from a small town and I don't belong to a very rich family. Should i collect money and move to a big town like New...

Thanks D H. You are great! :)

Not working My latex code is \begin{flalign*} E_1 & = \frac{e_{1max}}{\sqrt{2}}\\ & = \frac{N_1.{\phi}_m.w}{\sqrt{2}}\\ & = \frac{N_1{\phi}_m.2\pi.f}{\sqrt{2}}\\ \\ E_1 & = 4.44 N_1.{\phi}_m.f\\ \\ E_1 & = 4.44 N_1.B_m.A.f \end{flalign*} and after using \boxed in E_1 & = 4.44...

I want to enclose my final equation inside a box but i find no way to do that in latex. please help me out as soon as possible. Thanks!

sorry it was sine not cosine. so p will be minimum for max value of sine. i.e theta minus phi is equal to ninety. thanks tiny tim you really explained me in a very interesting nice and smart way. i am on phone so I'm inclined to use texting language. please ignore if you feel that my posts are...

Sorry, I made a mistake here. Here's the correct one For body B N = 150 cos 60 = 75 N T =\mu N + 150 sin 60 = 145 N For body A R + P sin\theta = 100 ......(i) \mu R + 145 = P cos\theta = 0.2 R - P cos\theta = -145 ...(ii)

that 60 degree is not the value of \theta. It is unclear in diagram but \theta is the angle made by force P on the horizontal. (block A).
