i have a question but no mark scheme so i can't see where I am going wrong. a mass, m, is dropped with speed zero from point O at time t=0 after time t it has traveled x. the body is subject to acceleration due to gravity and drag -mkv. (A) write the equation of motion: ok so i know...

thanks I am still new to stuff and thanks :cool:

is there a direct proof that an idempotent matrix with inverse, can only be an identity matirx i can't find about how id prove it i know A^2=A and A^-1 exists so too AB=BA its obvious to say elements must be 1 or 0 but finding an overal rule isn't obvious to me

its remainder and quotient...obvious now. thanks :smile:

Im given two polynomials: f(x) =(2x^6) + (x^5) - (3x^4) + (4x^3) + (x^2) -1 and g(x)=(x^3)-(x^2)+2x+3 find polynomials Q(x),R(x) in the set of R[x] s.t f(x) =g(x)Q(X) +R(X) and deg(R)<deg(g) Am i even in the right area? and something to do with manipulating numbers in C[x]...
