• Assume the function f is defined asf(x)=3.2cosx8.7sinx
• f(x)=3.2cosx8.7sinx
• Use the corresponding derivative rules to find the second derivativef(x)
• f(x)and evaluate that second derivative at x = -9.4.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)
• f(x)at x = -9.4 for four different values of the mesh sizes
• h = 0.2
• h = 0.1
• h = 0.05
• 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.
