Dear all,

I would like to solve the following function:

f:=sum(Y[i]*ln(t[i]), i = 1 .. n)+(sum(Y[i]*t[i]^beta[1], i = 1 .. n))*ln(theta[1])/theta[1]^beta[1]-(sum(Y[i]*t[i]^beta[1]*ln(t[i]), i = 1 .. n))/theta[1]^beta[1]+(sum(Y[i], i = 1 .. n))/beta[1]-ln(theta[1])*(sum(Y[i], i = 1 .. n));

solve(f = 0, beta[1]);
Error, (in solve) cannot solve expressions with sum(Y[i]*t[i]^beta[1], i = 1 .. n) for beta[1]

It is still possible to solve the function in beta[1], so that beta[1] can be made explicitly. Thank you.
Please Wait...
