05 More errors

Today's lectures follows last's lecture on numbers and discusses the accumulation of errors in algorithms. The key insight is that the total error consists of an algorithmic error (also known as the approximation error), which typically decreases with increasing the computational cost and a round-off error, which increases with the number of operations or the computational cost.
