thanks how do u know what a, b, c and d are equal...i got the rest

1) integrate x^3/(2-x^2) 2) if f(x)= (ax+b)sinx + (cx+d)cosx, determine the values of the constants a, b, c and d such that f'(x)=xcosx thanks

will do, thanks

how do u know?

is that similar to arg(z-2/z+2)=pi/2 how would u do that?

fahh, dont any people do this?

anyone does it? whats it like? career opportunities? :)
