1 Derivative of $f(x)$ with respect to a constant such as $1,2,3,\ldots 9999$. 2  Derivative of $f(x)$ with respect to a function such as $\ln(x)$, $\sin(x)$, $\cos(x)$.hat I would like to understand is: Why does (derivative with respect to x) make sense but $(\text{derivative with respect to} (\lambda x \to 2))$ and. $(\text{derivative with respect to} (\lambda x \to \ln(x)) $ do not seem to make any sense to me.
75th ranger regiment 75RR: Elite, large-scale special operations The 75 th Ranger Regiment, known as the 75RR, is the U.S. Armyâs premier large-scale special operations force, and it is made up of some of the most elite Soldiers in the world. The Rangers specialize in joint special operations raids and joint forcible entry operations. Being a Ranger is an honor shared by a distinct few.
From 1954 to the early 1970's, the Army's goal, though seldom achieved, was to have one Ranger qualified NCO per infantry platoon and one officer per company. In an effort to better achieve this goal, in 1954 the Army required all combat arms officers to become Ranger/ Airborne qualified.
