Find the derivative of equation s(t) = sec(sqrt(t))

[joy08]

I need help finding the derivative of this equation: s(t)= sec ? t.

so far I got sec1/2? tan 1/2? t

Do you possibly mean "the derivative of the function"...? If you are indeed differentiating the "equation" (using, I would guess, implicit differentiation), then: with respect to what variable (not "t", of course) are you differentiating?

Also, are you familiar with the Chain Rule?

Thank you!
