With this background, here is your assignment: Assume the function f is defined as f (x) = 5cosz 4sinz Use the corresponding derivative rules to find the second derivative f " () 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 "' () at x = 1.7 for four different values of the mesh sizes o h=02 h=01 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: h central difference approximation exact second derivative error = approximation - exact value 0.05 0.025 Note: To avoid round-off error, retain the maximum possible number of decimal places in calculations of the error
