Question

y=1/4tan(6x-4) find second derivative

Answer 1

is it
\[y = \frac{ 1 }{ 4 }\tan(6x-4)\] ?????????

Answer 2

yes

Answer 3

okay we will use chain rule over here
\[\frac{ dy }{ dx} = \sec^2 (6x-4)*\frac{ d }{ dx }(6x-4)\]

Answer 4

this is the first derivative did u follow the step?

Answer 5

yes
thank you for helping me out

Answer 6

in the previous step i forgot to put 1/4
\[\frac{ dy }{ dx } = \frac{ 1 }{ 4 }* \sec^2(6x-4) * 6\]

Answer 7

now take the second derivative and show what u got?

Answer 8

18sec^2(6x-4)tan(6x-4)

Answer 9

yeah u r right

Answer 10

thank you for your help

Answer 11

pleasure

Answer 12

I have other question.:).y^6+x^3=y^2+10x (0,1)
