Hi i really need this answer:)

take the derivative of (sin(3-x))^2 like it was x^2, you just have to remember to multiply by the derivative of what's inside the "squared"

oo sick thats so helpful thanks a million
anonymous
  • anonymous
hah wats the answer just to confirm?
anonymous
  • anonymous
why dont you give me what you came up with and we'll see if it looks good
anonymous
  • anonymous
so i know it starts of as 2(sin3-x)
anonymous
  • anonymous
then multiply by the derivative of sin(3-x)
anonymous
  • anonymous
so the derivative of sin(3-x) is? uhm cos(3-x)? correct?
anonymous
  • anonymous
not quite, remember you have to multiply by the derivative of what's inside the sin
anonymous
  • anonymous
waah i hate calc. ok so the derivative of that is 1?
anonymous
  • anonymous
is it?
anonymous
  • anonymous
lol idk im asking u!
anonymous
  • anonymous
what's the derivative of 3-x, you probably know that
anonymous
  • anonymous
-1!!!
anonymous
  • anonymous
good
anonymous
  • anonymous
so then its 2sin(3-x)(cos3-x)(1)
anonymous
  • anonymous
what'd we just talk about though?
anonymous
  • anonymous
usually you wouldn't leave it as times 1 just so you know, that would just go away
anonymous
  • anonymous
f(x)=sin^2(3-x) f'(x)= 2sin(3-x)(cos (3-x))(-1) Evaluate for 0: f'(0) = -2sin(3-(0))(cos(3-(0)) f'(0) = -2sin(3)cos(3) f'(0) = 0.279415..

Hi, Mr. Euclid. He forgot the -1, I have no intention of stealing your thunder ;)

  • anonymous
no i don't care, and yeah i was already telling him but he disappeared

if you want some math to do here is a test for you http://floridamao.org/PublicPages/TestArchive.aspx?qy=true&category=States&style=Limits+%26+Derivatives&year=2005

Ooh cool, saved to bookmarks. I really should be doing my area between two curves calc homework, funny that I choose to do other math as an effective self distraction instead of more traditional routes (video games and food). Firefox hates this site, trying it with Chrome now. Love the name by the way. Euclid's Fifth Postulate and hyperbolic geometry ftw.
