Prove for each pair of expression f(n) and g(n) whether f(n) is big O, little o Ω,ω or Θ of g(n). Use limits to find these. For each case it is possible that more than one of these conditions is satisfied:1. f(n) =log(n2^n), g(n) = log(sqrt(n)2^(n^2))2. f(n) =nsqrt(n) +log(n^n), g(n) =n + sqrt(n)logn
Need this expression solved for mu. This can be done using a symbolic toolbox, however it needs to end up being mu = function (theta, m, L, g). If using MATLAB or something similar, run the code to make sure it works.
