2 students are passing
a test of n questions with
the same chance to find each one
Show the chance that they both
don′t find a same question is ((3/4))^n
let f:R→R be a continuous function then
show that
(1) if f(x) = f(x^2 ) ∀ x ∈R then f is a constant
function
(2) if f(x) = f(2x+1) ∀x∈R then f is a
constant function
find the transfer function of the state
model of the system given by
x^• = determinant (((0 1 1)),((0 0 1)),((−1 −2 −3)))x+ determinant (((0 0)),((1 0)),((0 1)))
and determinant ((y_1 ),(y_2 ))= determinant (((1 0 0)),((0 0 1)))x
