NOTE The author of this question requires you to use the formula dy - Ay Error ~ Ay where Ay = f(b) - f(a) (f(b) is the value of the function at the approximation and f(a) is the value of the function at your "anchor" point). Let y = sin(2x). If Ax = 0.2 at x = 0, use linear approximation to estimate Ay Ay Find the percentage error error = %
