this mathod is wrong this is lineor form of equ  multy bhot side 1/cosx than u can slove

regards,,

opr  N=cosx  hai. glti se 2 dfa cosx cosx likha gya. sory for tht

shahmeer yar ap galti kar rahy ho agar ap apni he de huwi equation may daykhay to cosx kay sath minus ka sign hay means -cosx to uska differentiate karny kay bad

y=-(cosx)

dy/dx= -(-sinx)

so

dy/dx= + sinx

this one is correct

not -cosx

yes yes, equ. extct he hai. i checked it again. '-' miss ho gya tha mere se. so exct equ. ka IF nikalna he ni hota hain. it's already exct equ.
