find the differential of dy of the given function.

y=3x-4sec(2x-1)

The answer i got was dy=(3-8sec(2x-1)tan(2x-1))dx

I am not entirely certain i got this correct. if you could check this for me, it would be a big help. :)

  • math -

    Looks fine to me
    d/dx sec x = (sec x tan x)(der of x)
