    Our Solar System name?

    Ok, so I've been passionately researching my latest novel idea as it takes place in an extremely far fetched future with long range interstellar travel and all that and the brink of controlled time modulation etc... While doing this, I've been able to name every site, system, planet of...

    Rawr! Stuck on ODE (linear 1st order!)

    Thank you so much guys, I was banging my head on my desk with that. The solution y = \frac{(x+8)^{9}}{13} + (8^{5} - \frac{8^{13}}{13})(x+8)^{-4} checked out.

    No luck. Oh well, thanks for your time I guess.

    Ok lemme look at that, thanks.

    Rawr! Stuck on ODE (linear 1st order!)

    I didn't think it'd matter... I get the same thing. y = \frac{(x+8)^{9}}{13} + C_{1} | where C_{1} is just another arbitrary constant that will satisfy the equation given the initial conditions. I get the same constant regardless... 8 = \frac{8^{9}}{13} + C_{1} C_{1} = 8 -...

    Rawr! Stuck on ODE (linear 1st order!)

    Homework Statement Solve the initial value problem: y'+\frac{4y}{x+8}=(x+8)^{8} , y(0)=8. The differential equation is linear. Homework Equations N/A The Attempt at a Solution I can see that the equation is in the form y' +P(x)*y = Q(x) so I'm like "easy, lemme get an...

    What should I do to get into MIT, CalTech, etc?

    Two-Fish I thoroughly enjoyed your edgy, quasi-Yoda-like contributions to what may have been just some ordinary necro thread!

    2log(x-1) + logx = logx + log4

    There you go! I'd have kept log(4) on the right side and then just solve for x.

    2log(x-1) + logx = logx + log4

    Well the first step is just an algebra step, you have log (x) on both sides of the = sign, so the equation can be reduced. When that happens you are left with a log (of something) = log (of something else) when this happens you can sort of drop the log and just solve for x.

    2log(x-1) + logx = logx + log4

    Hey there, ok it looks like you have some exact same term on both sides to begin with, so those can just cancel out right? This leaves you with a log of something = a log of something else, that should simplify it down nice for ya.

    Improper Integral (Calc II)

    Ugh... Sorry to waste your time. The limit is pi/2, all I had to do was take the limit and I was already done lol. For some reason I thought there would be no limit for the arctan and that was bothering me.

    Improper Integral (Calc II)

    Been doing some calculus review to knock the rust off for this coming fall semester and I got stuck... Homework Statement From Stewart's book (Early Transcendentals: 6E): (7.8 pg517 #69) Determine how large the number "a" has to be so that: \int\stackrel{\infty}{a}\frac{1}{x^{2}+1}dx <.001...

    Vector Question(addition?)

    Although, my answer is wrong Hmm, I just gave this a shot myself and got the same magnitude for the r vector, it looks correct to me...! What did you get for the angle?

    Two algebra (1?) problems

    Hey Cyril, I think Mark pretty much covered everything but I wanted to chime in about coefficients as it sounds like you're just getting your pinky toe wet with Algebra. The 0.06x from your first problem has two parts and you were correct in that they are multiplied together (the number and...
