What does the D9 in this mean?
350197
D9-trans-tetrahydrocanabinol is commonly referred to as D9-THC.  The D9 stands for delta 9 (Δ9-tetrahydrocannabinol).  The words alpha, delta, etc. are used to denote specific isomers of the same compound.  In this case also, D9-THC refers to an isomer of the same compound C21 H30 O2 . The chemical name is (−)-(6aR,10aR)-\n6,6,9-trimethyl-3-pentyl-\n6a,7,8,10a-tetrahydro-\n6H-benzo[c]chromen-1-ol.

What the heck does that mean?

Delta simply means "change in".  It is used to indicate a change over a given period of time.  If you are looking for an "average" value, you use "delta N over delta t".\n\nThe "d" as it is used in your question refers specifically to a change over an infinetessimally small period of time.  If you are dealing with a specific point in time, in other words an "instantaneous" value, then "d" is used rather than delta.

They might be ICD-9-CM diagnostic codes. You could try to figure them out using the ICD-9-CM guidelines, downloadable (free) from the CDC at http://www.cdc.gov/nchs/datawh/ftpserv/ftpicd9/ftpicd9.htm\n\nIt would be easier to call your doctor's office and ask them what it meant, then you can get any other questions you have about the diagnosis answered at the same time.

Its either d or e. It should be a deshielding effect by the pi electrons. There is some gobbledy-gook showing up in my browser so I can't tell d or e is the pi symbol.

its measure of defect present in any software component.it is broadly defined as:\n\nd.d.=defects/thousand lines of source.\n\nif we talk about any source code it will be:\n\ncode defect density=defects/thousand lines of code

The notation 's', 'p', 'd', and 'f' originate from a now-discredited system of categorizing spectral lines.\n\ns= sharp\np= principal\nd= diffuse\nf= fundamental

y=sqrt[(144-9x²)/16]\n\ndy/dt= dx/dt.(-9*2x/16)/(2*sqrt[(144-9x²)/16])\n\ndy/dt=4y.(-9x/16)/(sqrt[(144-9x²)/16])\n\ndy/dt = 4y.(-9x/16)/(y)\n\ndy/dt=-9x/4\n\ndy/dt is maximum when x is minimum\n\nx(min)= - 144/9\n\n=> dy/dt=144/4 =36.\n\ndy/dt is maximum when x= - 144/9\n\n(could be all wrong huh)
