1. Zapping With d 1

   Find the differential of each of the following expressions; zap each of the following with \(d\). Note that all italicized letters are variables:

   1. \[f=3x-5z^2+2xy\]

   2. \[g=\frac{c^{1/2}b}{a^2}\]

   3. \[h=\sin^2(\omega t)\]

   4. \[j=a^x\]

   5. \[k=5 \tan\left(\ln{\left(\frac{V_1}{V_2}\right)}\right)\]
