Vectorama Lite

Vectorama calculates the component and magnitude/direction forms of a vector as you size and rotate it. It also displays the formulas and calculations so you can crunch the numbers on your own.

Use the calculator buttons (MC, M+, etc) to perform vector arithmetic: addition, subtraction (negate the vector with the "Flip" button, then add), and dot product.

The free Lite version is fully functional except that the numeric keypad (useful for precise and fast entry of exact values) is disabled.

Useful for:
- Vector homework
- Physics problems (force, gravity, acceleration, work, etc)
- Right-triangle/pythagorean theorem problems
- Polar/cartesian conversion
- Unit circle exploration

Feedback/suggestions/reviews are welcome.

Directions:
- Drag on the graph to move the vector around
- Pinch to zoom, or double-tap (origin = zoom in, edge = zoom out, elsewhere = fit)

- Precisely adjust individual components in the tabbed area at the bottom
- Numbered buttons nudge the vector at .01/.10/1.0 intervals
- Slider adjusts within the current range of the graph
- "Quad" button zooms to the current quadrant
- "Flip" button negates the current component when x or y is selected, and negates the entire vector (useful for vector subtraction) when r, theta, or "More" is selected

- MC = memory clear, M+ = add current vector to memory, M* = calculate dot product between current and memory vectors, MR = load the memory vector as the current vector
- Contents of the memory vector are faintly visible on the graph
