I go in the TI connect...

Hi, I'm having a lot of trouble trying to set up a process for calibrating turbine flowmeters for use in fuel rigs. Basically, I have a calibrated "master" flowmeter in series with the uncalibrated turbine flowmeter. I need a process that will give me the line of best fit across the...

std:: was not used in my previous experiences with programming in C/C++ but in xcode,it requires you to put 'std::' in front of both cout and cin. i get an error that reads 'cout' was not declared in scope. I am sure it is something very trivial but in insights would be appreciated.

I am allocating a value of 0.1 to a position in an array and it seems to be storing itself as 0.10000001. The problem is that once all the values in the array have reached 0.1 the average should be 0.1 and the loop stops, but as it is being stored as 0.1000001 the average is > 0.1 and the loop...

Hi, I don't know if it's some mistake that I've been committing without realising it, but the Latex facility provided by this forum has given me no end of trouble. The following are two major problems I've faced: 1) Post preview generates a database error if there is too much latex in one...

i'm not sure if this is the right place but I'm trying to get my head around derive 6 and i have a couple of questions that don't seem to be coming out right... d^{2}y/dx^{2} + 8dy/dx + 16y = (4e^{-4x})(sinx+cosx)^{2} ; y(0)=y'(0)=0 so i inputed DSOLVE2_BV(8, 16, (4·^(-...

I'm having some trouble with LaTex. Here is the LaTex code: \frac{1}{q_{2}} = \frac{A q_{1} + B}{C q_{1} + D} And it should produce this: \frac{1}{q_{2}} = \frac{A q_{1} + B}{C q_{1} + D} Here, it's produced just fine. But in TeXnicCenter, it produces this instead...

It's been a year or two since I gave up, so I guess I'll subject myself again. Why am I unable to add funds to a Paypal account from a Credit card? It's like it has never occurred to them that anyone might want to do this. I am not about to attach my bank account information to anything...

Hi, I have a 3HP motor running continuously. After about 5 years it has stopped, flicked breaker and it continued. That happened a few times. More recently, now 10 years, it stopped and wouldn't start. I tried a few things, but turning the motors shaft seemed to get it to work when power was...

I'm not really new to Digital Electronics, but this is confusing the crap out of me. My school's started a DE class and at the moment we're getting all our equipment worked out and stuff, but for some reason NONE of our IC's work. We're using a 9-volt batter with a 7805 regulator for 5 volts...

I'm trying to use the nlinfit that MATLAB has to fit a sinc^2 function, but it keeps telling me that my coefficients have the wrong inputs. Here's basically what I am doing. %driver.m y = [intensity points]; %I actually have a bunch of intensity points, but I don't want to list them x =...

Hi everybody. I'm relatively new to C++ and am having an issue. What I need to do is take in several files and then do some data processing in each of them separately. I've tried to do this several ways and nothing has worked so far. Below is my last attempt. Basically, each file is...

I've been having difficulty with this problem and can't seem to find where to start. Any help would really be appreciated. A water insect maintains an average position on the surface of a stream by darting upstream (against the current) then drifting downstream (with the current) to its...

So I bought the magic bullet blender last xmas and loved it. Used it for several months and then one day it just stopped working. The blender base that you press down on just didn't respond anymore. So I thought it died. I bought a new base on ebay and that didn't work either, so I thought...

Hello Everyone, I am trying to model a circuit using Orcad Pspice 9.2 I am trying to solve the time when the opamp saturates with maximum voltage operation of 10v and -10v. I am applying different voltages to the circuit, when I do the transient analysis, i am not getting the right time. For...

I was just reading about JFETs. I decided to try a circuit in multisim. Connected a N-channel jfet(2N4222), the source is connected to ground and the drain is connected to +12V. The gate is not connected. But there is a drain resistor(1K) connected between gate and ground to drain any gate...

I recently purchased an HP50G as I caught my TI-89 giving me incorrect results when solving simultaneous equations. However I can't get the 50G to do anything but tell me invalid syntax. I am using MSOLV as follows: MSOLV('[x/60+x/15+(x-y)/5-15=0][y/2+(y-x)/5+5=0][x,y] This is the syntax...

I am sure it is not right, it seems able to go backwards far more than the other, and has less control, it has little pain until it goes backwards, the only outward sign of malfunction is that it is quite hot ? is this a doctor thing or wait and see thing?

Today in class we learned about diodes. Our prof explained to us that the only manual way to find the correct states of the diodes is guess and check. Each time, we ended with one correct circuit; that is Kirchoff's laws coincided with the diode constraints. Now I'm doing this circuit on my...

I have an interesting problem: I'm moved into university and people can't join custom games I create in warcraft 3. However, people CAN join games I create in starcraft. What would cause this? How do I fix it?

Hello - I worked out this problem but I got a wrong answer. First, I used the Pythagorean theorem to find the radial distance between A and each charges. So 1.2m divided by 2 (= 0.6), then the square root of .6 squared + .6 squared = .849, which is the radius. Then I used Coulomb's...
