problem: find y=f(x) if dy/dx = 3y - 5 I don't know differential equations but I'll give it a try: Let z=y-5/3 dz/dx=3z guess z=ae^(bx) dz/dt=abe^(bx)...
This is something I stumbled on a few years ago. In an equilateral triangle, take point S and connect the vertices through S to the opposite sides at a, b,...
Please if u know how to do Linear differential equations: My friend gave me a solution to x^2 dy/dx - 3 xy = 1/ x^2 next step he shows that dy/dx - 3/xy =...

In a message dated 2/3/2006 5:28:28 AM Central Standard Time, ... No. (1/x^2)/x^2 = 1/x^4. What I don't see is how -3xy becomes -3/xy after both sides of the...

... Take a look at http://ocw.mit.edu/OcwWeb/Mathematics/18-03Spring2004/VideoLectures/index.htm Professor Mattuck is quite good and will keep your attention. ...
I'm not sure about your question, but one way of solving this is to make the substitution u=y/x^3 u' = y'/x^3 - 3y/x^4 ==> x^5 u' = x^2 y' - 3xy = 1/x^2 ==> u'...
the correct ans is y=1/3 (Ae^(3x) + 5)whereA=e^c dy/dx=3y-5 or,dy/(3y-5)=dx log(3y-50\3=x+c 3y-5=e^(3x+c) 3y=e^(3x+c)+5 y=1\3(Ae^3x+5)whereA=e^c brianejensen...

... Finally had a chance to read your post carefully. Your proof is quite simple, and very elegant. You certainly didn't misrepresent the difficulty, but it...

I need to repost this solution for S that lies on a side of the eq. triangle. If you let S=a and from this point draw perpendiculars to the other two sides of...
I have a question about testing normality in small samples: I know that I can use Shapiro-Wilk test, which is for small samples. But I'm wondering, what would...
