You are in the hospital waiting room, waiting for the birth of your sister's first baby. A nurse comes out and tells you that you may have to wait a while because your sister is going through "failure to progress." Your mom hears this and becomes worried. What would you tell your mom? Not to worry, that simply means that labor is taking longer than they expected. That the fetus is probably going to be born breech. That the fetus is in "distress" and an emergency cesarean section will likely be performed. The cervix has not dilated at all.

Consider the interpolation nodes {tn-1, tn}. (a) Write down the Lagrange polynomial interpolant P(t) for the function f(t,y(t)) at the nodes above. (b) Consider the IVP y(t) = f(t,y(t)); as in class, integrate both sides from t = tn to t = tn+1. Approximating the resulting right hand side as f(t,y(t)) dt ~ P(t)dt, integrate the Lagrange polynomial P(t) from (a) exactly to determine bi and b2 such that ytn+1-ytn ~ h * f(tn,ytn) + b * f(tn-1,ytn-1), This is the two-step Adams-Bashforth method. Your answers bi should be given as fractions (not approximate decimals).
