Do you know any way to check the answer to this question, cause I think i got this
Thanks for your answer.
Unforunately, I don't know the answer. Could you please show the solution way. How did you solve it ?
here you go,yeah my last few steps got deleted due to technical difficulties,however the process for calculating a₅ continues for a₆ and a₇,so assuming no mistakes on a₅,I’m good
also I’m pretty Sure there are no mistakes for everything up until the 4th power term[I backed up my answer by Solving for y” and then differentiating 1 and 2 times respectively]
I’m not sure if I’m wrong though
