hello,
i'm trying the mathematica demo by doing some basic mathematics.
now i'm stuck at rewritting a fraction.
could somebody please help me by telling me how to rewrite:
1/((x-1)(x^2+x+1)) to A/(x-1) + (Bx+C)/(x^2+x+1)
or do i have to do that manualy?
and can mathematica find the values for A, B and C ?
Solve[eqn1==eq2,{A}] doesnt solve the problem, and subsituting
x with 1 doesnt either.
tia,
