Question

CAN SOMEONE CHECK IF I HAVE THE RIGHT ANSWER? for Find the derivative of the function. y=Ine^x

Answer 1

\[y=\ln(e^x)\]like that? :o

Answer 2

y(prime)=1/xe^x+e^x1/x

Answer 3

no w.out the ( )

Answer 4

is the power inside the log or no? :)

Answer 5

nope :l as it is written initially

Answer 6

y=Ine^x

Answer 7

are you allowed to do any simplifying before you take the derivative? or is derivation suppose to be your first step?
because there is a really nice simplification here :o

Answer 8

umm u simplify 1st

Answer 9

spose a = e^x
a' = e^x

D [ln(a)] = a' /a

Answer 10

\[\ln e=1\]
gives you a nice place to start :D
y=1^x

Answer 11

not 1^x

Answer 12

if anything

ln(e^x) = x ln(e) = x

Answer 13

his equation is y=(ln e)^x

Answer 14

really? hmm

Answer 15

wont i 1st rewrite In?

Answer 16

ln e then is just a constant ...

Answer 17

???????????????????

Answer 18

lol that one always confuses people :)

Answer 19

you need to get comfortable with natural log lilly!! :D
ln e, means --> e to what power = e

Answer 20

should go something like this eh
\[a^x=y\]
\[x=log_a(y)\]
\[x=\frac{ln(y)}{ln(a)}\]
\[x~ln(a)=ln(y)\]----------

derive
\[ln(a)=\frac{y'}{y}\]
\[y~ln(a)=y'\]
\[a^x~ln(a)=y'\]

Answer 21

okay now i KNOW i am failing that quiz on FRIDAY ......:[[[[[[[[[[

Answer 22

interactmath.com its a free site similar to MathLab. lots and lots of practice problems there to work on :)

Answer 29

solving derivatives in one calculus books is the same as solving them in all the others

Answer 30
