Question

lim sin(180/n)*n
n->infinity

Answer 1

1/pi

Answer 2

put n=1/x

Answer 3

But I got pi

Answer 4

how did u solve ?

Answer 5

ok,
lim x->0 sin (180x)/x = lim x->0 180 sin(180x)/(180x) = 180 (1)
sorry ,even i am getting 180 or pi.
you are correct

Answer 6

So, lim sin(x/n)*n = x
n--->infinity

Answer 7

???

Answer 8

i think u have doubts in range of sin function....is it ?
otherwise yes, its x

Answer 9

oh.....
sorry I think it is
lim sin(x/n)*n = x *pi/180
n--->infinity

Answer 10

n is in radians.
so x is in ?
if x is in degrees, then x*pi/180 is right.

Answer 11

Because in above when x=180 we got pi
