In the extraction of Cu, bessemerisation is used as a part of purification and during the process Cu gets auto-reduced. So, v consider bessemerisation to be useful for self reduction of Cu !

in the extraction of Cu....& in the third step of bessemerisation

2Cu2S +3O2 -> 2CuO2 + 2SO2

Cu2S+2CuO2 -> 6Cu +SO2

as cu is reduced, v can assume that this is used in the reduction of Cu......

analyse the theory.dont just believe in wat ever he gave.....think- y are v using this formula..once u understand wen to use wat formula u'll know hw to solve a problem...before solving problems from HCV first go through the examples he has given!

and the books u hav are the best ones available and dont get mix up with all buks at once.....follow a single book for theory and then see examples available in dcpandey and HCV and then start solving problems on your own! and don't start doing irodov now..start only after u hav confidence in the topic...

yes, eg . for a straight line which doesnot cut the x axis, i.e., if the line is parllel to x axis ,it doesnot hav any maxima or minima, so the number of roots are zero;

taking log on both sides

logy= logxsinx  +log (sinx)x

logy = sinxlogx  + xlog sinx

differentiating

1/y * dy/dx  =  sinx / x  +   logx cosx   +   logsinx     +      x cosx/sinx

dy/dx = y * (sinx/x   +cosxlogx +logsinx  + xcosx/sinx)

         =  (xsinx +sinxx) ( sinx/x +cosxlogx +logsinx +xcosx/sinx)
