hey, good morning, mimi
anonymous
  • anonymous
use the product rule :) y' = u'v + uv' where : - u = x^4 - u' = 4x^3 - v = e^x - v' = e^x just plug them in ^_^
anonymous
  • anonymous

  • anonymous
so if i set it to zero, what would my critical numbers be?? sorry i am really bad at exponential and log functions
anonymous
  • anonymous
you'll have to factor first to find the zeros, lol it's alright, when you factor and get the zeros, your zeros will be the critical numbers and to find the points , you'll have to plug them in the original function to get the y's :)
anonymous
  • anonymous
ok thanks sstarica, you are really helping me out tonight! :)

anonymous
  • anonymous
great ^_^ , don't panic if you don't know how to solve one question, if you take alot of time on it, skip it and proceed to the other questions, when you're done and there's still time, go back to the questions that you've skipped
anonymous
  • anonymous
and you'll do just fine ^_^
anonymous
  • anonymous
Good luuuuuuuuuccckkkkk
anonymous
  • anonymous
lol , yep :)

You'll be fine. Just be strategic. Don't spend too much time on a question if you're stuck.
anonymous
  • anonymous
exactly~
anonymous
  • anonymous
oh, keep a bottle of cold water near you
anonymous
  • anonymous
I dont keep bottles of cold water near me... when I lived in Africa for some time, I used to because it is so freaking hot there and my body needs alot, but here, in this cold mystical country, I might prefare hot chocolate instead :)
anonymous
  • anonymous
If I were you, I'll stay away from hot chocolate before any test, it has milk and this will make you drowsy
anonymous
  • anonymous
Last semester, before my calculus I midterm exam in an hour, I drank hot chocolate assuming it to give me energy, but instead I got drowsy and sleepy and messed up the test
anonymous
  • anonymous
nah.. I wont take anything to the exam.... because i will concentrate really hard on the questions and I will forget to drink anyway...
anonymous
  • anonymous
you'll have breaks right?
anonymous
  • anonymous
no
anonymous
  • anonymous
If you can get your hands on Powerade or something, drink that
anonymous
  • anonymous
how long is it? ._.
anonymous
  • anonymous
the exam is VERY small and short
anonymous
  • anonymous
lol, loki that's not good for the heart, not even redbull ._.
anonymous
  • anonymous
powerade just replaces electolytes
anonymous
  • anonymous
good, small short, easy simple, and you'll be done in an hour :)
anonymous
  • anonymous
his nerves have to work
anonymous
  • anonymous
his nerves are working just fine after such a heavy breakfast
anonymous
  • anonymous
I don't like those power drinks
anonymous
  • anonymous
not healthy
anonymous
  • anonymous
it is only 3.5 hours
anonymous
  • anonymous
take chocolate with you just in case
anonymous
  • anonymous
and thats maths, some physics, some chem, and an engish essay and motivation letter
anonymous
  • anonymous
too much concentration will cause you to get hungry
anonymous
  • anonymous
especially when you have 3 sciences
anonymous
  • anonymous
I guess Red Bull is a better choice, once I remember drinking like 4 cans, and it made me focus like a laser :)
anonymous
  • anonymous
._. redbull is NOT GOOD
anonymous
  • anonymous
and 4 cans? are you crazy?!
anonymous
  • anonymous
you got luck in not getting a heart attack that's for sure.
anonymous
  • anonymous
lucky*
anonymous
  • anonymous
red bull's awesome
anonymous
  • anonymous
who cares if it is good or not, what I care about is to concentrate and have an energetic mind
anonymous
  • anonymous
correct
anonymous
  • anonymous
yeah, you'll care when you fall ill won't you?
anonymous
  • anonymous
your heart repairs
anonymous
  • anonymous
no it doesn't
anonymous
  • anonymous
don't take it that slightly
anonymous
  • anonymous
it does...i saw it on oprah once
anonymous
  • anonymous
you have to take care of yourself , both of you.
anonymous
  • anonymous
well oprah is not always true
anonymous
  • anonymous
the doctor was
anonymous
  • anonymous
all organs can slowly repaire themselves, yeah I saw it somewhere too... the guys name was Paul Bragg or something, he was this health pioneer
anonymous
  • anonymous
I know someone who has a weak heart, that cannot be repaired
anonymous
  • anonymous
that's genetic, though
anonymous
  • anonymous
4 cans? what has gotten into you.
anonymous
  • anonymous
his repair mechanisms are shot from birth
anonymous
  • anonymous
not genetic loki
anonymous
  • anonymous
it just happened
anonymous
  • anonymous
my repair mechanisms are GREAT, I once got "messed up" and had some bones broken in the leg and fist and wrist... but in about 1 month I was able to perform just as I did before....
anonymous
  • anonymous
effects won't show up now, but they will certainly will later , just be careful , try not to drink those power drinks too much guys.
anonymous
  • anonymous
you are young, what about later?
anonymous
  • anonymous
it'd be just one drink of red bull ... ;)
anonymous
  • anonymous
it is not like I drink red bull like water every day.... that would waste too much money, so I can't :)
anonymous
  • anonymous
well, try not to drink too much , both
anonymous
  • anonymous
AND my dear, I don't drink any alcohol, so I have to "conpensate" with Red Bull :)
anonymous
  • anonymous
yeah I know, again not too much
anonymous
  • anonymous
^_^
