    Data repeatability (statistics question)

    Homework Statement I am trying to see if two sets of data represent the same values or not. I have: Mean1 = 9.3155, stdev1 = 0.1334; mean2 = 9.3040, stdev2 = 0.1248; N1 = N2 = 1000; I got these values from my data using MATLAB (std() and mean()); Homework Equations z =...

    A problem with display on an oscilloscope

    Hi! I have acquired an older LeCroy oscilloscope from someone. It used to work, but now when I plug it in, the screen is orange (normally letters and lines and things are orange, but now the whole length of the screen is). It doesn't take up the entire screen, but I cannot see any menus where...

    Is architecture the right path for me?

    Well, are you going into EE because your dad works in the petrochem industry (and probably makes a lot of money) or because you find it interesting? My goal in electrical engineering would never be to work in petrochem. It pretty much stands against all I believe in. My choices right now would...

    Is architecture the right path for me?

    Hi everyone, I'm thinking about my edumacation a bit and would like some advice. I am currently in 3rd year of electrical engineering (I love it, don't get me wrong), I also adore drawing and sculpturing. So for a few months I've been thinking about doing architecture after this degree. It's...

    How do I integrate ax on the plane y=7?

    I don't know, it just says plane y=7.

    How do I integrate ax on the plane y=7?

    Well I guess ax is a unit vector in the x direction, so it must be constant. But how do I figure out the limits of integration for x and z?

    How do I integrate ax on the plane y=7?

    Homework Statement The Attempt at a Solution I get parts a and b, but I don't know what to do for part c. I can write a double integral with dx and dz (because y is constant) and substitute y=7 in, but I'm not sure how to integrate ax... Any hints would be appreciated.

    Never Learned How to Study Advice?

    I'm kind of in the same boat (second year Electrical Engg though) - I'm currently sitting at about a C in Circuits II and am fully relying on the final exam to bring it to a reasonable level, which isn't generally a good policy, nor is it a policy I usually follow. However, I did a very similar...

    Trying to create an if/else statement for a string

    I agree with Mark44, You can have the 4 conditions in your if statement or you can convert the character the user enters to upper case (or to lower case). But that isn't necessary, it just makes the runtime shorter.

    Excited hydrogen atom and wavelength

    This is my guess at how to do this question (I'm referring to my high school notes for this...) Basically, you can use the good old E=(hc)/lambda. Wavelength (lambda) will equal hc/E. Now, if you look at this diagram: [PLAIN]http://castlelearning.com/review/reference/phys6.gif you...

    Reducing Circuits to Their Simplest Form

    For circuit 2? That wouldn't be correct. Every resistor is connected to nodes (point where 3 or more wires meet) at both of its ends. You can only claim that resistors are in series if they do not have a node inbetween them. ---R1----R2---- Resistors 1 and 2 are in series ---R1---R2----...

    Simple DC Circuit (That I Can't Solve)

    I see, but pay attention to the resulting polarity of your 8 ohm resistor when you're doing that. (ie, is the top end of it positive or negative?).

    Reducing Circuits to Their Simplest Form

    Don't worry about it then :) It's a transformation that would allow you to change circuit 2 into battery+resistor circuit. Since you said you thought it could be solved, how did you plan on reducing on?

    Another DC Circuit (But more complicated with a SWITCH and Capacitor)

    That's right. After a very long time, the capacitor becomes essentially an open circuit.

    Simple DC Circuit (That I Can't Solve)

    Why are you assuming that value for the current? The voltage drop across the central "branch" depends on which way the current through it goes. Try writing out the two KVL equations. You shouldn't have to assume any values for currents.
