• VECTORS
• vector.mws Shows Maple commands for standard operations on vectors including differentiation and substitution.
• arclength.mw Computes the length of a curve by approximating it by a piecewise linear curve.
• standard-surfaces.mws Introduces the standard surfaces - cylinder, cone, ellipsoid, paraboloid.

 
• DIFFERENTIATION
• approx2d.mws Computes the linear approximation of a function of two variables and shows the error and the percentage error in the approximation over different neighbourhoods of the expansion point.
• critical-pts.mws Shows critical points need not be local max or local min.
• maxmin.mws Motivates visually the method for optimizing functions over bounded regions.
• lagrange.mw Motivates the method of lagrange multipliers by studying a constrained optimistaion problem using contours.
• mixed-lagrange.mw An optimization example which requires unconstrained optimization (critical points) as well as constrained optimization (Lagrange multipliers).
  

 
• MULTIPLE INTEGRATION
• suminteg.mws Approximates the mass of a non-rectangular, non-uniform plate by subdividing the plate into small squares.
• threesurface.mw Describes how to plot a solid bounded by z=0, z=y, and y=1-x^2.
  
• foursurface.mws Describes how to plot a solid bounded by z=0, z=3-y, y=x^2 and y=2-x^2.
  


• VECTOR FIELDS
• vectorfield.mws Plots the vector fields (a) water flowing across an infinite cyl;inder (b) gravitational field due to a unit mass.
• flux-flow.mws Plots a vector field and a curve and computes the flux across and the flow along of this vector field across the curve.
