Show that if we had used regular perturbation to solve exercise 7.6.19, we would have obtained x{1, e)= a cost+ea f tsint+ cos 31 - cost)] +0(e) . why is this solution inferior? 7.6.19 (poincaré-lindstedt method) this exercise guides you through an improved version of perturbation theory known as the poincaré-lindstedt method. consider the duffing equation +x+ex'= 0, where 0

Use the grouping method to factor x^3+ x^2 + 3x +3

Iam stuck on one problem. my mind is in absoloute vacation mode. i literallty just need to finish this to be done will give brainliest and all my points if i have to! 1- point free throw and 2- point feild goal. he made 35 shots, and scored 62 points how many of each shot did he make in 1 minute? (i already did the math. he made 8 1-point free throws and 27 2-point feild goals.) 1. write two equations for the problem. (i had a major brain fart.)
