Find instantaneous rate of change of 7/3z^2

  1. "Find the instantaneous rate of change of w with respect to z if w=(7/3z^2)"
    excuse the primitive equation...any help???

  3. Just differentiate it with respect to z.

    Is that w= (7/3)z2 or w= 7/(3z2)?

    I suspect the former which should be easy to differentiate using
    (zn)'= n zn-1. If the latter, write it as w= (7/3)z-2 and use the same rule.
