Title: Calculus Help (No book to help me!)
Post by: Walter on April 07, 2008, 06:46:32 PM
Alright, so our teacher is retarded and giving us homework that is not in our textbook which will probably cause me to fail yet again. So I need a bit of help from you geniuses. If anyone knows how to do this please post quick, it's due tomorrow.

QuoteDetermine wether the function is a solution to of the differential equation xy' - 2y = x^3 * e^x

y = x^2 (2 + e^x)


QuoteSolve the following differential equations

(2 + x) y' = 3y


QuoteFind the particular solution that satisfies the initial condition

du/dv = uv sin(v^2); u(0) = 1


I chose a couple of the hard looking ones. Plz help me.  >.<

This isn't fucking NSider. We don't add "ah" or "eh" to the end of everything and laugh at it.

What the hell?
I just got to indefinite integration. ;_;

Calculus is a bitch. I hate it so much. We were finding areas of 3D objects earlier and that was pretty easy. But this bullshit is ridiculous. I just don't understand what I am trying to do...  edumacate;

And apparently my teacher is giving us worksheets for the rest of the year.  baddood; I am a terrible note taker, I need examples in the book to guide me or I am fucked.

Is this AB or BC Calculus?
I'm just learning regular calculus, which is more manageable. I don't know how to find an antiderivative for any of those problems. This textbook I'm using now is written poorly.

I am currently taking advanced placement AB Calculus. You haven't learned how to take anti-derivatives of ln or exponential functions yet? Or is it because it is in an equation form? For me, it is because it is in some weird equation form. I don't really understand what I am trying to do and it's not in my book. =/

uh not a big fan of differential equations but could probably do it if the notation wasn't so silly doodthing;

You are my only hope man... I have failed 3/5 grading periods this semester. If I fail the next two... lol I don't even care. But please help.
