-
- If you find DQua useful then let me know. Any gifts, cash and even bug
- reports are greatly appreciated ¿-) If you want the current version of
- DQua (and a wad more progs) then send £3 (or equivalent of £5 plus
- [money or gifts]) to me.
-
- DQUA REQUIRES KICKSTART 2 (V36) OR GREATER
-
-
- Usage
- =====
-
- DQua is started by double-clicking its icon or typing DQua at the
- Shell prompt.
-
- All input to DQua is through the use of 3 string gadgets: a, b, and c.
- Each gadget represents a value related to the general quadratic form:
-
- ax + bx + c = 0
-
- All input to DQua must be in this form. So for example to solve the
- following equation, brackets must be multiplied out and the result rearranged.
-
- (t+1) + 2t = 8t
- => (t+1)*(t+1) + 2t = 8t
- multiply out brackets => t + 2t + 1 + 2t = 8t
- rearrange => t - 4t + 1 = 0
- | | |
- / | \
- / | \
- a = 1 b = -4 c = 1
-
- Simply enter the values and hit the 'solve' gadget to solve.
