I mean find lim x-->0 {sin0 +sindx +sin2dx +sin3dx +...+sin(ndx)/(n+1)} where ndx=90

mean value theorem for integrals?

No not mean value theorem... Here I just want to find the avereage value

ndx=90 n=90/dx Now, lim x-->0 {sin0 +sindx +sin2dx +sin3dx +...+sin(ndx)/(n+1)} lim x-->0 {sin0 +sindx +sin2dx +sin3dx +...+sin(ndx)/(90/dx +1)} lim x-->0 {(sin0 +sindx +sin2dx +sin3dx +...+sin(ndx))dx/(90+dx)} |dw:1359042392858:dw|

Now, from there I will get 1/90 Which surely not CORRECT
anonymous
  • anonymous
Now, If I do ndx =pi/2 then I will get 2/pi

@experimentX can u PLZ help

this should be close to zero.|dw:1359042684509:dw|

Well 90 is degree, you surely can't use that in these calculations ? pi/2 is appropiate.
experimentX
  • experimentX
hmm ... is 90 really degree?
anonymous
  • anonymous
And yes that was what I was going to ask... Why does it matter
experimentX
  • experimentX
degree is just a notation made for the sake of ease ... radian is the actual value.
experimentX
  • experimentX
you might have noted lim x->0 sin(x)/x = 1 or ... as approx .. when 'x' is very small, sin(x) ~ x ... this never works for degree ... it sounds funny.
anonymous
  • anonymous
So actually sin(pi/2 radian) =1
anonymous
  • anonymous
And we supposed pi/2 radian =90 degree
experimentX
  • experimentX
yes!! radian is more natural measure of angles.
anonymous
  • anonymous
So, is the correct answer 2/pi
experimentX
  • experimentX
yep!!
experimentX
  • experimentX
compare these with the area bound by the curves with x axis an 0 and pi/2
