h(x)=((x−x^2 )/(x+1))
we defined this function on
R−{−1}→R
1) Study the variations of h then
draw up its table of variation.
please sirs i need your kind help
Two system of rectangular axes have
the same origin. If a plane cuts them
at distance a, b, c and p, q, r
respectively, then prove with the help
of an appropriate diagram that :
(1/a^2 ) + (1/b^2 ) + (1/c^2 ) = (1/p^2 ) + (1/q^2 ) + (1/r^2 )
