does (x+h)log(x+h) = xlog(x+h) + hlog(x+h) ?

why's diffraction grating better than double slit experiment for finding wavelength of a wave

thanks guys...but i have trouble understandin the expression for the magnetic field intensity i.e B = F/m where 'B' is magnetic field intensity, F is force experienced by The unit pole and 'm' is the strength of another magnet... just confused how this relation came
-
does it mean the north magnetic pole of a magnet of +1 strength?
-
the intensity of magnetic field at a point is defined as the force experienced by a unit north pole placed at that point . WHat does unit north pole mean ???
-
why does spectrum of hydrogen have many lines though it has only one electron???

please help to figure out>>>>

when the image forms at infinity how can we proove M= D/F M= MAGNIFICATION D= LEAST DISTANCE OF DISTINCT VISION F= FOCAL LENGTH
-
i have prob understandin the following proof......... IN THE CASE OF SIMPLE MICROSCOPE IF IMAGE FORMS IN INFINITY THEN HOW CAN WE PROOVE= MAGNIFICATION(m) = D/f where 'D' IS LEASE DISTANCE OF DISTINCT VISION AND F = FOCAL LENGTH

sorry guys about some mistake ....but i am still confuse in this binomial expansion.....can u explain that part =>HOW IS C(n,2)x^2 = (n(n-1))/2!) OR C(n,3)x^3 = (n(n-1)(n-2))/(3!) of this equation....
-
CAN ANY ONE PROVE THIS? ( n! ) /( r! (n-r)! ) = ( n(n-1) )/ 2!

if somebody can help in BINOMIAL THEOREM
Prashan_punk replied to Prashan_punk's topic in Mathematics
thanks for helping -
Can somebody describe BINOMIAL THEOREM in a effective way....ABout the its "general term", "middle term" ...........thanks to anyone who will describe it
-
THanks guys...for the help......i may post some other questions ....coz i need to get prepared for examx
