1.
sinh^2 x/(1 + cosh^2 x)
2.
sqrt[(1 + sin x)/(1 - cos x)]
pls solve them completely..............rates assured!

now is the question
y = sinh ^(2x) /1 +cosh^(2x)
or
y= sinh^2 x/(1+cosh^2 x)
in first case take log on both side
log y =2x log sinh -log(1+cosh^2x)
now differentiate
dy /dx= y( 2logsinh - {[1/1+cosh^2x] cosh^2x log cosh *2
correct me if i m wrong
but surely we have to take log
rate me if i m right

@ chemicaltester
the 1st question is
y= sinh^2 x/(1+cosh^2 x)
