In how many ways can obtain polynomial from [PLAIN]http://im3.gulfup.com/2011-05-05/1304543619801.gif notes that c any coffieceints is in{0.1} also in how many ways can obtain even ploynomials?whats the probability that we can obtain P(1,1,1)=0

Homework Statement [PLAIN]http://hh7.net/Apr1/hh7.net_13016941501.gif Homework Equations these statement are false and i need counter example for each one The Attempt at a Solution for(ii) i can say that f(x)=x2-4 on [-6,6] for others i need help

the defintion of linear convergence is http://disk04.arb-up.com/i/00030/qbvg9pj513m1_t.jpg

how can i show that ?

Homework Statement Let u(x; y) be real, nonconstant, and continuous in a closed bounded region R. Let u(x; y) be harmonic in the interior of R. Prove that the maximum and minimum value of u(x; y) in this region occurs on the boundary. Homework Equations the theorem said that( a...

Hi What is the domin of f(x)= xlnx. I know that: domin of x is R and domin of lnx is x greater than 0 so the domin of them will be x greater than 0 but when I subtitude 0 on f(x) I find (o.\infty) and this form from LHopital Rule so what shall I do I use the first tip or I...

could you give other example : the example will be in discontinuoty on [a,b] but differentiable on (a,b) ok I will be greatfull for you if give me the example because this qeustion from the homework and tomorrow is the due day

I still thinking about this question but we know if the function is not continuous then it is not diffrentiable so the answer of question (3) is will be no example because he want the function be discontinuous on interval [a,b] and diffrentiable on (a,b) that's never ever will happen...

yes it is satisfyed the theorem

yes I mean closed interval [a,b] for example F(x)= 1/x on [0,2] F(x) is discontinuos at x=0 F(x) is differentiable on (0,2) and thank you so much

Homework Statement the rolle theorem said : suppose (i) F(X) is continuous on colse interval (a,b) (ii) F(X) is differentiable on open interval ( a,b) (iii) F(a)=F(b) then there is c on (a,b) such that F`(c)=0 the question is give an example : 1- satisfied (i)...

yes I tried to sketch it and I find only x=0 Are my answer is correct?
