A three layer neural network is shown in Figure $2\mathrm{.}19.$ The inputs are $0\mathrm{.}1$ and $0\mathrm{.}9,$ the learning

rate is $0\mathrm{.}8$ and momentum is $0.$

i$)$ Examine the error values in forward and backward sweeps as shown;

ii$)$ Determine which error value$($s$)$ is not correct and calculate the correct value.
