Exam 3 Review Topics, 2008


Basics: Concept of optimization, maximization and minimization with constraints. Indetermined forms of limit, and L’Hopital’s Rules. Regular partition of intervals, general Riemann sums, special Riemann sums: Left Point Sum, Right Point Sum, Midpoint Sum. Limit of Riemann sums. Definition of definite integral. Geometric interpretation of definite integral in terms of area. Average value of a function. Simple rules for definite integrals. Definition of anti-derivatives. Definition of indefinite integral. Fundamental Theorems of Calculus – part I and part II. Method of substitution. Finding areas between curves. Finding volumes by slicing, and by rotation.  


Techniques: Story problems in optimization: objective functions and constraints. Formulation optimization problems. L’Hopital’ rule for 0/0 type, ∞/∞ type, 0*∞ type. Hand calculation for left point sum, right point sum, midpoint sum. Memorize 2 special formulas: 1+2+…+n=n(n+1)/2 and 1^2+2^2+…+n^2=n(n+1)(2n+1)/6.
