What is the diffentiation of

log ( log y)  =  x logx   +   log (log x)

1 )   In a stationary wave pattern that forms as a result of reflection of waves from an obstacle the ratio of amplitude of an antinode and a node is 1.5   What percentage of the energy passes across the obstacle?

2  )  A uniform string of lenght L and total mass M is suspended vertically and a transverse pulse  is given at the top end of it . At the same moment a body is released from rest and falls freely from the top of the string. how far  from the bottom does the body pass the pulse ?

thank you

wer can i get the students solution manual of halliday resnick

hey i already have bansal questions but not the notes......newayz how much r u charging for notes..........

can anyone jus temme how to approach such problems.......that will be more then enough for me

Equal weights of mercury and I2(iodine) are allowed to react completely to form a mixture of mercurous Hg2I2 and mercuric HgI2 leaving none of the reactants . calculate the ratio of the weights of Hg2I2 and HgI2 formed?

thank you

Show that the function z = 2x^2 + 2xy + y^2 + 2y - 2x + 2 is not smaller than -3.

thank you

Let  f:[0 , 1]R be a continous function and f(0) = f(1) .  Prove that for some k  [0 , 1/2 ] ,  f(k) = f(k+1/2).
