Taking Integral and Optimization using Integrate, Optim and maxNR
...ntegral of this function with respect to y, such that x would appear in the output after taking integral. f(x,y)=(0.1766*exp(-exp(y+lnx))*-exp(y+lnx))/(1-exp(-exp(y+lnx))) y in (-6.907,-1.246) It is doable in maple but not in R. At least I could not find the way. p.s: result from maple is: g(x)=dilog*exp(0.001000755564*x)+0.5*ln(exp(0.001000755564*x))^2-dilog*(exp(0.2876531111*x))-0.5*ln(exp(0.2876531111*x))^2 Where dilog=integral(log(t)/(1-t)) for t in (1,x) Question 2- Then I want to optimize (maximize) the answer of the above integral for x. Assum x in (0,100) The answer should be somet...
