Dear Friends,
                       I am facing a problem to NSolve an  Elliptic
Integral like that.

f[x_] := Sqrt[(1 +
          0.176*Sin[m]^2*Sin[x]^2)*(1 + 1.018*Sin[m]^2*Sin[x]^2)/(1 -

g[m] = 0.159*Sqrt[1/(-9*10^(-6) + Sin[m]^2)];

NSolve[NIntegrate[f[x], {x, ArcSin[0.003/Sin[m]], Pi/2}] == g[m], m]

Here I want to get an "m" value such that integration value = g[m].

This NSolve shows problem, please could any body tell me how to get
exact m value.
