I think the answer of it was e^(e - 1) but I'm not too sure if it's correct

Homework Statement Suppose the Wronskian of W(y1, y2) [0] = 1 y1, y2 are solutions to the differential: y'' + e^xy'+ tanx = 0 Find W(y1, y2)[1] ? The Attempt at a Solution So I'm thinking of using Abel's theorem, where p(x) = e^x W(y1, y2)(0) = = c e^{\int{- e^t dt}} So, 1 = ce^{e^{-t}} But...

http://www.urbandictionary.com/define.php?term=bump I know this was a while back but did you end up getting the problem solved?

Can I bump this? I've got a similar problem and I'm trying to derive it using my notes which derives the gas law using the pressure on an entire face of the box. It works out since multiplying the length L of the box against the area of the face gives the volume V of the box. But in this case...

Hi I've got an introductory Linear Algebra course that is using Elementary Linear Algebra with Applications by Bernard Kolman, David R. Hill and from what I can ascertain, it's a garbagety textbook [https://www.amazon.com/dp/0130457876/?tag=pfamazon01-20]. A lot of of the negative reviews...
