I have a question on how to obtain the final answer for a question I came across earlier:
I got up to here:
And from here I was not able to solve for 'n' without graphing it on my graphics calculator and finding the x intercepts. Is there any possible way to do this algebraically, or have I made an error somewhere within my working?
Thanks
