Question

differentiate

Answer 1

\[f(x)=\sqrt{12x-x^7}\]

Answer 2

The rule for the square root is :\[(12x-x^2)'/2\sqrt{12x-x^2}\]

Answer 3

sorry x^7 not 2

Answer 4

now can you differentiate (12x-x^7) ?? @ billie4120

Answer 5

@billie4120

Answer 6

you there @billie4120 ??

Answer 7

I thought it was
\[\frac{ 1 }{ 2(12x-x^7)^{1/2} }\]

Answer 8

yes you're right but (12x - x^7) is a function so you have to differentiate this as well

Answer 9

This is the chain rule

Answer 10

do you understand it?

Answer 11

Ok let me know if you need help @billie4120

Answer 12

do I just take the derivative of 12x-x^7

Answer 13

yes and then divided by the 2sqrt(...)

Answer 14

so would it be
\[\frac{ 1 }{ 2\sqrt{12-7x^6} }\]

Answer 15

No I said the derivative of the function divided by the double of the square root

Answer 16

got it??

Answer 17

not sure
\[\frac{ 12-7x^6 }{ 2(12x-x^7)^{1/2} }\]

Answer 18

that so true
Good job

Answer 19

that's it?

Answer 20

yea

Answer 21

except of you have initial values for x ??

Answer 22

no there are no values for x
Thank you.

Answer 23

ok so that is it!! and you are welcome
