Itâs a cost-benefit analysis: If it costs you 3 hours weekly to do the wash, but costs you $30 to send it out â that is $10 per hour. But if you bill more than that at your business â or stand to get a raise if you use those three hours to learn new skills, earn a degree, etc., it is worth the investment.
Coordinate Rules for Rotations. In general, we can state the following coordinate rules for (counterclockwise) rotations about the origin: For a rotation of 90o: (x, y) --> (ây, x) For a rotation of 180o: (x, y) --> (âx, ây) For a rotation of 270o: (x, y) --> (y, âx)
2.004 Fall â07 Lecture 18 â Friday, Oct. 19. Root Locus sketching rules. Wednesday. â¢ Rule 1: # branches = # poles. â¢ Rule 2: symmetrical about the real axis. â¢ Rule 3: real-axis segments are to the left of an odd number of real-. axis finite poles/zeros. â¢ Rule 4: RL begins at poles, ends at zeros.
