3. \(h\left( z \right) = \ln \left( {2z} \right)\sin \left( {2z} \right)\) uchun differentsialni hisoblang.
Yechim
Bu muammo uchun haqiqatan ham ko'p narsa yo'q.
\[\require{bbox} \bbox[2pt,border:1px solid black]{{dh = \left( {\frac{1}{z}\sin \left( {2z} \right) + 2\ln \left( {2z} \right)\cos \left( {2z} \right)} \right)dz}}\]Oxirida \(dz\)-ga tegishni unutmang!
