( Help !! ) I have to finish an essay over the summer holiday （ 4000 words essay ) and i decided to do it on cubic polynomial. I will investigate different approaches to solve cubic function ( 3 ways ) the general formula method, the cardano's method and the trigonometric and hyperbolic method. I will then compare them and evaluate their pros and cons. Also i will mention how to use the newton's method to approximate polynomials. However, it is not enough but I couldnt think of anything else. Someone said that I could do something on numerical stability of cubic function but i fail to search any related articles at all...... What is it？　Is it a good idea ? Also, do you think it is a good idea to apply the methods that I mentioned to real life situation? So I might think of something from daily life and compose a cubic function, then use 3 different methods mentioned to solve it. What do you think about that ?? I dont know what to do with my life so plzzzz help ..... I wanna do well but i feel like i wont. Thank you so much for your time
