I would like to solve an equation of this kind
NIntegrate[f[n],{n,0,x}]==0 (f[x_]=Sqrt[1+x+x^2...)
where x is the searched value, and f cannot be integrated analytically.
NSolve[NIntegrate[f[n],{n,0,x}]==0,x], tries to evaluate
NIntegrate[f[n],{n,0,x}] before assignin a numerical value to x and
returns an error.
How could this calculation be done without having to write a program
that searches the root?
Thanks.
