write 1+tan^2 x as sec^2 x
e^1/2 log sec^2 x = e^log secx
therefore
y = sec x
dy/dx = sec x tanx

the method is...
let number ofFe2+ be x and number of Fe3+ be y
so x+ y=93
balancing charge with that of oxygen we get
2x + 3y = 200
solving these 2 eqns we get y= 14
so %age = 14/93 *100= 15 % approx

and wat abt IT and ECE??
which shud be the first choice among these??

rite now its comp but dunno wat it wud be 4 yrs down the lane..
