n ∈ Z +, đặt fn(x) = sin x sin 2x · · ·sin(2^nx). prove that: |fn(x)| ≤ 2/ √ 3 |fn( π /3 )|, ∀x, n. please help me!!!

you cant answer this dummy

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
