======================================= S2009 notes on problems 3.1-4,6,16,18,26 ======================================= 3.1-4 ===== The answer "x=5, y=4" is the unique solution, as reported by the book. Submitted work is expected to display the solution details, which include documented toolkit steps of swap, combo, mult. Please do not display arithmetic steps. Preferred is a frame sequence which ends with last frame x=5, y=4. Each frame uses exactly one of the 3 rules: combo, swap, mult. 3.1-6 ===== The answer is "no solution" because of a signal equation, obtained with the toolkit of 3 rules: combo, swap and mult. A signal equation is a nonzero equation having no variables, like "0=1". 3.1-16 ====== The answer is "no solution" because of a signal equation, obtained with the toolkit of 3 rules: combo, swap and mult. A signal equation is a nonzero equation having no variables, like "0=1". Because there are 3 variables x,y,z, please develop a frame sequence, in which each frame uses just one of the 3 rules, ending with a frame that has a "0=1" equation. 3.1-18 ====== The book reports "No Solution" which is correct. Display a frame sequence with documented toolkit steps swap, combo, mult, ending in a last frame that contains a signal equation "0=1" followed by the statement "No Solution" or "Inconsistent." 3.1-26 ====== The constants are A=23, B=21 in the formula y=A exp(11x)+B exp(-11x). Follow 3.1 Example 8. ===end of 3.1 problem notes===
