CalcTool 3

Version

History

Version 0.8

1. Some labels were chopped off in on Windows platform; this has been fixed.
2. Symbolic calculation of divergence and curl on vector field panel has been added.
3. Domain panel on Deriv panel is now hidded as default.
4. Circular domain panel has been slightly reformatted.
5. "Net Area" is now invisible as default on Int panel for line integrals.

Version 0.7

Version 0.6

1. Added "Deriv" panel. This provides the ability to visualize slices of surfaces that yield curves that can be used to visualize directional derivatives.
2. Symbolic computation of partial derivatives is provided.
3. Numerical calculation of gradient and visualization of gradient is provided.
4. The ability to change the direction of slices (and hence the direction of the derivative) is added via a slider.

Version 0.5.5

1. Acceleration vector was not being computed in certain cases. This has been fixed.

Version 0.5

1. Added ability to graph both tangent and unit tangent vectors on parametric curves.
2. Added ability to graph both acceleration vector on parametric curves.

Version 0.4

1. Added slider to parametric curve graph to move tangent/normal/binormal vectors interactively.
2. Added ability to graph up to 10 points, and connect these points with a line, and/or form a closed loop.
3. Added ability to graph rectangular surfaces of form y=g(x,z) and x=h(y,z).
4. Added circular domain option for rectangular surfaces.
5. Parametric curves did not graph the max value for "t". This has been fixed.

Version 0.3

1. Added Dot/Cross tab to compute and visualize dot products and cross products.
2. Fixed bug where vectors parallel to (0,0,-1) would not graph correctly.

Version 0.2

1. Added option of graphing xy plane.
2. Added functionality to all tangent/normal/binormal vector boxes.
3. Changed layout slightly.

Version 0.1

1. First version with basic functionality. User can graph points, vectors, parametric surfaces, parametric curves, and rectangular surfaces in 3D.
