WEBExample: Use the trapezoidal rule to numerically integrate f(x) = 0:2+25x from a = 0 to b = 2. Solution: f(a) = f(0) = 0:2, and f(b) = f(2) = 50:2. I = (b¡a) f(b)+f(a) 2 = (2¡0)£ 0:2+50:2 2 = 50:4 The true solution is Z 2 0 f(x)dx = (0:2x+12:5x2)j2 0 = (0:2£2+12:5£22)¡0 = 50:4 Because f(x) is a linear function, using the trapezoidal rule ...

WEBEven though the symmetric Newton differentiation scheme gives bet-ter accuracy, there is a trade-off as it is much more computationally de-manding (i.e. it requires many more calculations) than the non-symmetric method. 5. In this exercise we are going to check the symmetric Newton’s quotient and

WEBLet us first make it clear what numerical differentiation is. Problem 11.1 (Numerical differentiation). Let f be a given function that is only known at a number of isolated points. The problem of numerical differ-entiation is to compute an approximation to the derivative f 0 of f by suitable combinations of the known values of f.
