Question

Find dy/dx by implicit differentiation.
4 x**2 - 5 y**2 = 16

Answer 1

what do you mean by ** ?

Answer 2

4x^2-5y^2=16

Answer 3

is it a power?

Answer 4

oh ok

Answer 5

i got dy/dx = 8x/5y

Answer 6

4x/5y actually

Answer 7

when you differentiate implicitly (dy/dx) you treat y as a function of x

Answer 8

ok

Answer 9

i got teh answer i will bump up your score

Answer 10

8x - 5* 2y* dy*dx = 0
sd/dx = 8x/10y = 4x/5y

Answer 11

ty

Answer 12

yw

Answer 13

how do i give you score

Answer 14

you apply the chain rule to y^2

Answer 15

just click on best reponse

Answer 16

really? i thought it was only the power rule

Answer 17

wouldnt this be chain rule (4x^2)^2

Answer 18

yes - but you are taking y to be a function of x so it amounts to the same thing

Answer 19

to be honest i cant remember the power rule
plz remind me
