Question

how would i find the derivative of sec(x)tan(x) ?

Answer 1

i would use product rule correct?

Answer 2

yea use the product rule so that (d/dx) secxtanx = (secx)[(d/dx)tanx] + [(d/dx)secx](tanx) where (d/dx)secx = secxtanx and (d/dx)tanx=sec^2x...so just plug that in and you should get something like secx(sec^2x+tan^2x)...idk whether your supposed to use identities to simplify more or what..but yea directly using the product rule..that's what i got
