• Assume the function f is defined asf(x)=10cosx8sinx
• Use the corresponding derivative rules to find the second derivativef(x)and evaluate that second derivative at x = 1.8. 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 estimatef(x)at x = 1.8 for four different values of the mesh sizes
  • h = 0.4
  • h = 0.2
  • h = 0.08
  • h = 0.024
