Hey all, I seem to be having some trouble finding the solutions (roots) to this equation:
0=210-10(e^(x/30) + e^(-x/30))
I got it down to this lol:
21=e^(x/30) + e^(-x/30)
and it seems like it should be easy, just I can't seem to simplify it down enough to be able to take the natural log from both sides
Any help would be greatly appreciated,
thanks!
