check out the givn link... it contains the answer to ur question (m not doing copy-paste, cuz u urself can surf the site, to knw wat exactly u need to learn )

yeah 1 / cosec t = sint t


nd integrating sin t wrt t, we have -cos t ...

well, C/C++ is taught to evry engg studnt in 1st yr, irrespctiv of branch

for learning C/C++ book by e balaguruswami (ANSI C) is gud..it has xplained almost evrything...besides this, u can try 'Let us c, by yashwant kanetkar' .... its also gud

whr li x is the lograthmic integral function...

basically this is not in JEE syllabus... still if u want to knw, here's the link http://mathworld.wolfram.com/LogarithmicIntegral.html
Catalogs Discussion Forums -> Organic Chemistry -> hey!!! wic book z the best for organic chem for proper concepts??? wat -> Go to message

dnt go for finar, its the ultimate book..not for learning concepts..but for strengthning the already knwn ones...

 for proper concepts, study Morrison-boyd.. its gud... nd for practice, u can have arihant's material ...if u r having someone to guide u , as thr r some mistakes in it.... or u can even solve the fiitjee or BT's package...thr problems r also gud!!

 

Catalogs Discussion Forums -> Physical Chemistry -> why can't the electron exist within the nucleus. hurry plz -> Go to message
This Post 0 points    (Olaaa!! Perrrfect answer.   in 0 votes )   [?]
this can be xplained thru the uncertainity principle..

radius of nucleus is of the order of 10-15 m

the maximum uncertainty = 2r = 2 X 10-15 m



thus,  

this upon solving will give V > 3 X108 m/s which is not possible...

thus electron cannot exist within a nucleus

for 2nd question, its defined only when log (cos 2pix) > 0

=> cos 2pix >= 1

=> cos 2pix = 1

=> 2pix = even multiple of pi

=> x is an integer....

 

 

 

nd...pls correct ur 1st question..

 = x + 2x + 3x2 + 4x3 + ..... nxn-1

u knw that 1+x +x2 + x3 +... + xn = 1-xn+1/ 1-x

differentitaing, u'll get the answer,

x + 2x + 3x2 + 4x3 + ..... nxn-1 =  {(xn+1-1) / (1-x2) } - {(n+1)xn / (1-x)}
