any more insights?
thanks for replying!
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...

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
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) ?
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..?
