I have a simple problem. I want to numerically solve Solve[ Integrate[ f[x,p]*g[x], {x,0,Infinity}] == V , p ] where f[] and g[] are defined functions, but the naive solution fails. W=1; g=0.5; q=0.1; V=2; fd[x_]:= PDF[ LogNormalDistribution[0,1],x ] ; Solve[ Integrate[ ((W +(x-p)*q)^g)/g * fd[x], { x, 0, Infinity } ]== V, p ] Solve::"tdep": "The equations appear to involve the variables to be solved \ for in an essentially non-algebraic way." The correct answer seems to be 1.5652 . How do I ask Mathematica to tell me this number? (My ultimate goal is to plot the solved p as a function of q.) /iaw
