This my first real posting so I hope goes well.
I was thinking about submitting a program I wrote for the apple that will
graph any function you want no matter how complicated. However this
does have its advantages and disadvantages.
Disadvantages:
1. It will treat a none continues graph as continues such a TAN function.
2. You must know a little bit of basic because the function is entered on
a line number.
3. It is very slow. Since it is written in basic and there is so many
calculations to make. You may wait up to one minute before the graph
is dispayed. If it is a complex function it may take longer.
Advantages:
1. It will graph any function in a nice way using the high res graphic
screens.
2. It will let you graph two functions and compare them on the same
screens or seperate ones.
3. It will let you move in two pointers to a desired point on the
graph and it will expand the graph over the entire screen between
those two points. It expands it over the X axis.
4. It graph on a four quadrant graph. It will show the two axis in the
correct proportion if the graph crosses either axis.
5. It expands the graph over the entire screen to get the best picture.
It is expanded on the Y axis in proportion to the most postivie or
negative point on the graph.
6. It will give the highest and lowest number on the X and Y axis for a
given graph. Numbers are not printed on the graphic screen.
There may be more advantages and disadvanteges, but the point is:
Would anyone be interested in this type of program. If I get enough
positive responds I may have it published in COMPUTE! magazine.
