According to the Existence and Uniqueness theorem, the differential equation (t−5)y′+ysin(t)=5t necessarily has a unique solution on the interval 0<t≤5. TRUE FALSE A numerical method is said to converge if its approximate solution values for a differential equation y′=f(t,y), y1,y2,...,yn, approach the true solution values ϕ(t1),ϕ(t2),...,ϕ(tn), as the stepsize h→∞. TRUE FALSE If a numerical method has a global truncation error that is proportional to the nth power of the stepsize, then it is called an nth order method. TRUE...
