Engineers have proposed a single-span suspension bridge across 8-km wide strait. The plan includes suspension towers 360 meters high at each end.

Use the Trapezoidal approximation ( n = 4 ) to estimate the total length of the cable (in meters) that is given by L=2integral^s₀ sqrt1+ 4H²/S⁴ x²dx I hope I got the formula right it is hard to input on this board. Please show all of the steps so I can better understand. I had this answered last night but I cant understand how to get Y1 y2 etc. All the help I have looked up glosses over it like its an understood simple thing and I'm stuck

Thank you
