Question

anyone who can prove this is right?
|sin(x)|<|x| for x≠0

Answer 1

A person gave me this (see attachment):
But what i don't understand is how the area is x/2

Answer 2

area of the circle is pi*r^2
area of the sector is x/2pi * area of the circle

Answer 3

and the triangle? don't we have one more side we don't know?

Answer 4

the base is the radius= 1
height is radius*sin x

Answer 5

Alrightie thank you.

Answer 6

wait a sec just fast why is it that area of the sector is x/2pi * area of the circle?

Answer 7

area of the sector is a fraction of the circle. example: if x= 2pi (360º) you get the whole circle. if x is pi (180º) you get half the circle. or in general x/2pi
