Ideas in this flowchart

• Area Calculation with Function F
• Calculate Y for X=A and X=B
• Y = F(A)
• Y = F(B)
• Find Area Using Integral
• Integral of F(x) dx from A to B
• Switch X and Y for Inverse
• Integral of F inverse(x) dx from F(A) to F(B)
• Difficulty Finding Inverse
• Calculate Area Using Box Method
• Larger Box Area = B * F(B)
• Smaller Rectangle Area = A * F(A)
• Subtract Smaller from Larger Box
• Resulting Area in Red
