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.

(down time for training was short) Army Rangers well they do not spend 20-25 years in the Rangers. Its is a short tour but a hell off a grind to make it but its back to regular army afterwards. They are quite a fit group. Marine force recon, they are good but they are not Seals.
