\[e ^{x^5-4x}(5x^4-4)\]
anonymous
  • anonymous
what would the second derivitive be?
anonymous
  • anonymous
use the product rule and chain rule on branlegr's equation

hmmm tried that... must not be typing right

e^(x^5-4x)*5x^4-4)
anonymous
  • anonymous
\[e^{x^5-4x}(20x+(5x^4-4)^2)\]
anonymous
  • anonymous
you dont need the product rule, all you need is chain
anonymous
  • anonymous
derivative of the outside times the derivative of the inside
anonymous
  • anonymous
e^x's derivative is e^x so consider x = x^5-4x
anonymous
  • anonymous
which becomes your inside function that you take the derivative and multiply it by
anonymous
  • anonymous
\[e^{x^5−4x}(20x^3+(5x^4−4)^2)\] I made a mistake... this is it
anonymous
  • anonymous
thats wrong. You are making it more complicated then it has to be Its just the derivative times the inside. Hes just entering it wrong Im pretty sure
anonymous
  • anonymous
nadeen is right ... thank you much
anonymous
  • anonymous
derivative of the outside times the derivative of the inside i mean*
anonymous
  • anonymous
No, you must use the product rule to find second derivative.
anonymous
  • anonymous
why are you taking the second derivative, Is that the problem?
anonymous
  • anonymous
yea nadeem is right, I didnt realize you needed the second derivative
anonymous
  • anonymous
Thanks....... for a second I thought I was going crazy
anonymous
  • anonymous
yes higher order
anonymous
  • anonymous
you never specified the problem correctly creeg no Nadeem, you are 100% correct
anonymous

cool

ln(15x7)−3y3=x3ey... guys want to help with thsi one .. i just need y prime.. cant get a right answer... tried like 1 hr on this stupid problem..
anonymous
  • anonymous
15x^7
anonymous
  • anonymous
I thought i did that already
anonymous
  • anonymous
no this is just an implicit problem
anonymous
  • anonymous
ln(x)= 1/x is the derivative umm -9y^2 y' is that derivative 3x^2 ey wont you have to do product rule
anonymous
  • anonymous
sorry this is it.. ln(15x^7)-3y^3=(x^3)(e^y)
anonymous
  • anonymous
\[(7−3x^3e^y)/x(9y^2+x^3e^y)=dy/dx\] is this not it?
anonymous
  • anonymous
just isolate y' this is easy
anonymous
  • anonymous
yes i know what to do saif... im just having a hard time either typing it in or im missing something
anonymous
  • anonymous
is this webassign?
anonymous
  • anonymous
cause webassign always messes up everything. I feel your pain
anonymous
  • anonymous
webwork .. prob the same.. i hate it
anonymous
  • anonymous
yea i bet!
anonymous
  • anonymous
and nadeen thats not the answer
anonymous
  • anonymous
What is it?
anonymous
  • anonymous
I dont understand Saif623 check my answer out and see if it makes sence...... you are suppose to differentiate implicitly... right?
anonymous
  • anonymous
my bad nadeen .. your right... i had to just fix a typo..
anonymous
  • anonymous
Man..........yall are trippin!
anonymous
  • anonymous
yea i got the same nadeem
anonymous
  • anonymous
you are right
anonymous
  • anonymous
lmao
anonymous
  • anonymous
lol... its been a long week.. how about tangent lines? e^(yx^3)−x(y^3+1)=9 at (-8,0)
anonymous
  • anonymous
i have finals on friday and I am doing your hw
anonymous
  • anonymous
lol
anonymous
  • anonymous
same here Bro...wtf... lol
anonymous
  • anonymous
that one will make my head explode with all my other studying im doing right now

anonymous
  • anonymous
no problem and Thanks Im gonna need it. 3 finals back to back
anonymous
  • anonymous
ya thats my schedule tomarrow..
anonymous
  • anonymous
Professors are so annoying. I have a webassign due to. Thank GOD I asked for an extension so its due after my finals
anonymous
  • anonymous
my math prof gave a quiz yesterday and this hw is do right now and the test is tomarrow night.. bad planning on their part .. whole class is pissed..
anonymous
  • anonymous
i bet! my professor randomly gives webassign homework so we will have like an hour to do it. Gets annoying
anonymous
  • anonymous
Lol when I see people asking on here problems to do with adding fractions. I wish that was my hw lol!
anonymous
  • anonymous
damn that would be frustrating.. lol ya ... alright well thanks again.. i got some more studying to do so ill cya around on here .. late
anonymous
  • anonymous
lates I got a lot of studying ahead of me to. Good Luck with the exam tomorrow
