Test 1. Linear quation


Test 1. Linear equation \(f(x)=ax+b.\)
1.1. Override attributes defined in jsxgraph.css.
1.2. Bounding box sets up quickly relative position of axis, grid unit, axis tick marks, and graph boundaries depending on the size of window (autoscale). This setup replaces originX, originY, unitX, and unitY. The number of units should abstract the number of pixels/unit.
1.3. Grid unit seems to be multiple of 5 units. Even with grid=false, grid lines in gray are shown at multiples of 5 (position of tick marks).
1.4. If tick marks are required, set axis option to false (default). Use minorTicks to control the number of intervals between major ticks (number of ticks = number of intervals – 1).
1.5. Draw special tick marks at arbitrary positions with specific height.
1.6. Specify size of point (2), fixed point position, and line thickness.
Name of point can be enclosed with standard HTML and CSS tags.
1.7. Add copyright label displayed in Bitstream Charter.
1.8. Update \(f(x)=ax+b\) (slope, x-intercept, y-intercept, and theta) when dragging.
Use anonymous function, var is optional, variable name is case sensitive.
1.9. Use MathJax and TeX notation for proper mathematical symbols as in printed textbook (starting and ending with $). In Javascript, TeX notation uses double slash wherever the documentation uses the single slash.
1.10. Use jQuery to update or enter an arbitrary position.
