A particle P of mass m is suspended from a xed point O by a light inextensible string of
length a. The particle is subject to uniform gravity and moves in a vertical plane through
O with the string taut
Assuming the standard expression for the components of acceleration in polar...
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...
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

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]...
