    What's the Best Minor to Pair with an EE Degree?

    I am trying to get my gpa to be high enough for grad school for ee, is a minor in music any good? since i am taking music courses, and thinking about doing ee with double major, and really really confused... any more insights? thanks for replying!

    Taylor series with summation notation

    yeah, but there's a x^3 on the bottom...

    Taylor series with summation notation

    Homework Statement f(x) = \frac{1-cos(X^2)}{x^3} which identity shoud i use? and tips on this type of questions? once i can separate them, then i'll be good thanks!

    If there's a book resting a a table, (Newton's third law concept)

    Homework Statement would you say that "the two forces exerted on the book ar ethe normal force directed up and the weight of the book directed down. These are equal and opposite to one another. By Newton's third law they are a third law force pair, so the normal force is always equal to the...

    Applying Partial Fractions to Solve Laplace Step Function Problems

    so no i have f(t) = 1-cos(t)+sin(t) - L{\frac{e^(pi*t/2)}{s(s^2+1)}} how do i get the last laplace?

    Applying Partial Fractions to Solve Laplace Step Function Problems

    step function - laplace... Homework Statement y"+y = f(t) f(t) = 1, t<pi/2 0, pi/2<=t<infinity The Attempt at a Solution i now have L{y} = \frac{1-e^(-(pi/2)s)+s}{s(s^2+1)} but how do i separate them and finish the problem? thanks

    Partial Fraction Decomposition: Nominator or Denominator?

    are you a math teacher? if you don't mind me asking!

    Partial Fraction Decomposition: Nominator or Denominator?

    haha brain fart on my part(i hope) thanks

    Partial Fraction Decomposition: Nominator or Denominator?

    ok, taking this example again: (s^2+2)(s^2+3)(s^2+5) would it be: 1 = (As+B)/(s^2+2)(s^2+3)(s^2+5) + (Cs+D)/(s^2+2)(s^2+3)(s^2+5) + (Es+F)/(s^2+2)(s^2+3)(s^2+5) ?

    Partial Fraction Decomposition: Nominator or Denominator?

    haha made a mistake... so with that, do i use As+ B? what if it's (s^2+2)(s^2+3)(s^2+5), ie, several s squares?

    Partial Fraction Decomposition: Nominator or Denominator?

    thanks for the answers! so let's say i have this long equation in denom. \frac{1}{(s^2+1)(s^2+4s-12)} i can factor one of them to look like: \frac{1}{(s^2+1)(s+6)(s-4)} but then how do I know if I should use A +B or As+B, Cs+D, etc..?
