Vectorama 1.3

Description
**Takes full advantage of the Retina display for high-res graphics! **

Vectorama calculates the component and magnitude/direction forms of a vector. Even better, this app 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), dot product, and cross product.

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. If you are an educator, contact me at the support site from your institutional email address for a free evaluation copy.

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
- "123" button toggles the numeric keypad (keypad: "+" = flip, "*" = set to 0.00, "#" = delete front digit)

- MC = memory clear, M+ = add current vector to memory, M* = calculate dot product between current and memory vectors, Mx = calculate cross product between current and memory vector (vectors extended to 3D space with z = 0), MR = load the memory vector as the current vector
- Contents of memory are visible as a faint "ghost" vector on the graph
What's new in Version 1.3
New:
- Cross product between current and memory vector ("Mx" on "More" tab)
- Up/Down arrow indicator on "123" button for numeric keypad (aesthetic change only)

Fixed:
- Label for the "R" slider maximum value didn't always match the actual maximum reachable by the slider
