One person will tell a story or guess about u based on ur username. The one above of corse. So yeah. Meh first!!! Lol
Sorry but I have no clue of what you just said... I'm on a call with 3 scientists trying to decrypt this code message...It will take 3 years so you have to wait!
Guess the solution to the differential equation t^3y''-ty'-y=2tcos2t Not gonna lie, the actual way to solve it is to guess at the solution and check if it works While it is a guess, it's not a total random guess you look at the right side and take derivatives and guess the solution is something that can take its form and its proportional to a constant. If the guess doesn't work then try adding an extra T to your guess.
