convert the secx to 1/cosx, that should help. And secx.tanx =sinx

What is the function you wish to differentiate? \[\ \ \ \ 9\sec{x} * 6x\\ = 54x\sec{x}\tan{x} + 54\sec{x}\\ = 54\sec{x}\ [x\tan{x} + 1]\]

when i replaced sec6x with 1/cos6x, this is what i got as my final answer, still wrong though. (0*1/cos6x)+(9+1/sinx*6)

I guess you made a mistake in writing the post, it says secx6x, the function is sec6x???

I crossed check, the answer indeed is 54*sec6x*tan6x. Just see if the equation was properly written. I mean I wrote 54sec6x.tan6x, try using 54*sec(6x)*tan(6x). hope that would work
