gutswarrior Posted June 24, 2009 Report Share Posted June 24, 2009 is y=e^(-x) a. differential equationb. linearc. non lineard. simple expression then prove... 3 reps if your answer is correct... thanks... Link to comment Share on other sites More sharing options...
e-hero-guy Posted June 24, 2009 Report Share Posted June 24, 2009 this is a shot in the dark...i say c...cause linear equqtions...r y=mx+b...its not different cause i think ive seen it before...its not a simpe expression cause if it was i wouls know the awnser...so my choice is © Link to comment Share on other sites More sharing options...
-Berserker- Posted June 24, 2009 Report Share Posted June 24, 2009 It's C. Link to comment Share on other sites More sharing options...
e-hero-guy Posted June 24, 2009 Report Share Posted June 24, 2009 sweet people agree with me...YAY!!!...lol...so is c the awnser Link to comment Share on other sites More sharing options...
gutswarrior Posted June 24, 2009 Author Report Share Posted June 24, 2009 why it is non linear? Link to comment Share on other sites More sharing options...

e-hero-guy Posted June 24, 2009 Report Share Posted June 24, 2009 and it isnt in liner form which is Y=MX+B Link to comment Share on other sites More sharing options...
gutswarrior Posted June 24, 2009 Author Report Share Posted June 24, 2009 i will give the reps after i get the answer... thanks...By the way, can you give me a picture of a speed cutter and a fabrication equipment and their uses... i need them now...3 reps for that...thanks Link to comment Share on other sites More sharing options...
OhHerro Posted June 24, 2009 Report Share Posted June 24, 2009 For a more elaborated answer: It cannot be A, as a differential equation is representative of a change in something (volume is the most basic one). A way to show that would be something like dV/dx, where dV is the change in volume and dx is the change in x, whatever x may be. Because your equation is not set up as such, it cannot be A. It cannot be B, because as previously stated, a linear equation is in the form y=mx+b, which your equation clearly isn't in. Finally, it cannot be D, as an expression is just an equation without the "y=" part. So what you have is an equation. The expression would be e^(-x). Therefore, the answer must be C, a non-linear equation. Incidentally, what math class are you in? Link to comment Share on other sites More sharing options...
gutswarrior Posted June 25, 2009 Author Report Share Posted June 25, 2009 i.m in a differential equation class.ok... how can you determine if the expression is linear or non linear in differential equation?give examples.3 for you tomorrow...e-hero-guy Link to comment Share on other sites More sharing options...
Dark Posted June 25, 2009 Report Share Posted June 25, 2009 I really wish I got here first, as then I would be getting 3 reps. On a side note, why did you put expression as one of the choices? A lot of people on YCM are dumb, but not THAT dumb. Link to comment Share on other sites More sharing options...

OhHerro Posted June 26, 2009 Report Share Posted June 26, 2009 that expression was just a choice... How can you be in a DiffEq class and not know the answers to the questions you're asking? This is seventh grade math at best. Link to comment Share on other sites More sharing options...

This is seventh grade math at best. lolThere is no such thing as a DiffEq class.It's either Pre-Algebra or Algebra I. :P Link to comment Share on other sites More sharing options...
