assume the function f is defined as f(x)=5cosx-4sinx, use the corresponding derivative rules to find the second derivative at x=1.7. be sure your calculator is in radians mode. note to avoid roundoff error retain at least eight decimal places. use the central differerence formula for the second derivative to estimate f" (x) at x=1.7 for four different values. h=0.2 h=0.1 h=0.05 and h=0.025 use calculated values to fill out table in picture with work shown.

. Assume the function f is defined as / (2) - 5 cosa A sing . Use the corresponding derivative rules to find the second derivative f " (x) and evaluate that second derivative at x = 1.7, Be sure your calculator is in radians mode. Note: To avoid round-off error, retain at least eight decimal places in your calculations. . Use the "central difference formula for the second derivative" to estimate f" (x) at x = 1.7 for four different values of the mesh sizes oh = 0.2 o h = 0.1 o h = 0.05 o h = 0.025 Note: To avoid round-off error, retain at least eight decimal places in your functional evaluations, and retain the maximum possible number of decimal places in calculations of the central difference approximation. . Use your calculated values to fill in this table: Calculate second derivatives: central error = h exact second difference approximation - derivative approximation exact value 0.2 0.1 0.05 0.025
