******** SKETCH THAT PARABOLA *********
This program is designed to give you a feel for all of the quadratic
equations called 'Parabolas' you've been doing lately. There are 4 basic
equations used here. They are:
2
1. y = ax + bx + c
2
2. y = x + a
2
3. x = ax + bx + c
2
4. x = y + a
If one of the above equations doesn't suit your needs, manipulate it.
For instance, in equation 4, when prompted for a value for a, enter 0; the new
equation is, 2
x = y .
This is a basic parabola. You can do the same with equation 2 and get
another basic parabola, with a different orientation. Add negative numbers;
get reflections, shifted parabolas. Assign zero to the variable 'a'. Watch
what happens.
When sketching a parabola, you assign values to the square variable to
get a number of coordinates. Such as. -3, -2, -1, 0, 1, 2, 3. You do this to
get a 'decent' shape of the parabola. Well here you don't have to figure that
out. The value of x squared or y squared is already assigned. This program
starts with negative half of your screen y-coordinates. That translates into a
large number and a very well defined parabola.
Enough said. Type, PARABOLA and then press enter to start the
program.
This program should come with 2 files. readme.doc (This one)
