Question

what is the correct differentiation for this question? @electrokid i keep getting 168z^6

Answer 1

"anti-derivative"
\[df=-28z^6dz\]

Answer 2

thats not correct either @electrokid

Answer 3

did you integrate?

Answer 4

nope..
check the integration

Answer 5

Differentiate each choice and see which one will give you what you started with.

Answer 6

\[\int x^ndx={x^{n+1}\over n+1}+C\]

Answer 7

so, what did you get?

Answer 8

B.?

Answer 9

@mathstudent55 that didnt really match up to the answer

Answer 10

its C

Answer 11

we do not really know the constant.. that s why it is "general"

Answer 12

and it does match @mathstudent55's answer.

Answer 13

oh ok i see what i did wrong..

Answer 14

@hayatabz1 Perhaps what is confusing is that you may have misread the problem.
You are being asked for the general solution of a differential equation. In this case, all you need to do is to integrate to get the answer. Then the problem asks you to take your answer and differentiate it to check to see if your solution is correct.
I think you misunderstood the directions, and you just differentiated what you were given instead of integrating.

Answer 15

yes i do see what i did wrong now thank you @mathstudent55 @electrokid

Answer 16
