Homework Statement
f(x) = (3 sin(x))/(2 + cos(x))
let x_0 be a number in (0, (2/3)*pi], and define a sequence recursively by setting
x_n+1 = f(x_n)
(1) prove that the sequence {x_n} is strictly decreasing sequence in (0, (2/3)*pi] and that lim x_n =0
(2) Find an integer k greater or equal...
Homework Statement
let f: R->R be a continuous function
Suppose k>=1 is an integer such that
lim f(x)/x^k = lim f(x)/x^k = 0
x->inf x->-inf
set g(x)= x^k + f(x)
g: R->R
Prove that
(i) if k is odd, then g is surjective
(ii) if k is even, then there is...
