Question

Differentiation ( I would be typing)

Answer 1

Suppose u and v are the functions of x that are differentiable at x = 0 and that

u(0)= 5
U"(0)= -3
v(0) = -1
v"(0) = 2

Answer 2

well, i mean, yes you can find some u,v unimited avtually, but i'm assuming you'll need to use integration by parts based off of the terms

Answer 3

\[\frac{ d }{ dx }(7v - 2u)\]

Answer 4

ahh ok, is there more?

Answer 5

no i solved the rest equation tool wasn't working

Answer 6

\[\frac{ d }{ dx }7v - \frac{ d }{ dx } - 2u\]

Answer 7

Would be like that

Answer 8

why do you have two minuses?

Answer 9

Quotient rule?

Answer 10

well, I mean I assume you were given \(f'(x)=\frac{d}{dx}(7v-2u)\)

Answer 11

yeah

Answer 12

and you want to find all possible u,v or just the value of f(x) at 0?

Answer 13

f(x) =0 there is only one value in the answer booklet

Answer 14

k so(this is like a hidden easy question in all the mumbo jumbo) if I rephrase it like this, does it make it a little more clear:\[(\frac{d}{dx}) [f(x)] =(\frac{d}{dx})[7v-2u]\]

Answer 15

yes

Answer 16

so what is your f(x)? or more easily put, what is f( u(0),v(0) )?

Answer 17

I will first find deivative of 7v and then - 2u and then add them together

Answer 18

\[\frac{ d }{ dx }7v + \frac{ d }{ dx } -2u\]

Answer 19

Is that correct

Answer 20

you don't need to find any derivatives

Answer 21

you are way overcomplicating it

Answer 22

the function is given without any work

Answer 23

I got 20 as the answer i know derivatives are given but that's how u would represent

Answer 24

is 20 correct

Answer 25

for f(0)? I dis not get anywhere close to that

Answer 26

please show your work

Answer 27

7*2 + (-2*-3) =20

Answer 28

that is f" (double prime aka second derivative) by the values you gave me, and we want f correct?

Answer 29

LOL sry but i dindn't get what u said but i got 20 and saw the answers and it is correct!

Answer 30

..uhm you've had me doing the wrong problem this whole time then

Answer 31

Maybe using full sentences, posing the full question, and obeying some more rules of grammar would be useful next time.

Answer 32

also note 1st derivative uses one ' second uses two "

Answer 33

ok
