1.

Answer» Right answer is (b) t+\(\frac{\DELTA t}{2}\) The explanation is: The first STEP of the ADI scheme is from t to t+\(\frac{\Delta t}{2}\). The second step of the ADIscheme is from t+\(\frac{\Delta t}{2}\) to t+Δt. Here, the intermediate step t+\(\frac{\Delta t}{2}\) is extra for the process and the RESULTS here are not actually needed.
