Slide 12 Are the heavy dampening and critical dampening curves the wrong way round? Also, should the resulting solution for m = a +/- bi be e^at (ACosbt + Bsinbt) ?
Slide 12: some of the exponentials have negative signs but should not
Slides 8 and 9 both have errors in writing the second differential with the squared shown on the numerator after the x. Slide 9 also has a 5 missing where it should say m=+/-5i.
