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!

Simplify: (B^{-1}A^{T})^{-1}B^{-1}(ABA)^{T}((AB)^{T})^{-1} Is the answer 1? thx

prospect ee major here. What would be a good minor to go with an ee degree? thanks.

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

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!

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...

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?

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

haha! well, thanks for the help!

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

haha brain fart on my part(i hope) thanks

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) ?

if was supposed to be a (s+6)(s-2)...

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?

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..?
