Lesson 2.4 Notes w/Student Companion YouTube Video > Mistake found @49'31", Example 5b, Factor 8y^2+18. After factoring 2 from the binomial, I wrote 2(y^2 + 9) instead of 2(4y^2 + 9). The final answer should be 2(2y + 3i)(2y - 3i).
Lesson 10.3 Notes w/Student Companion YouTube Video > Mistake found at 29'25", vector v is drawn in QIII. It should be in QII. Disregard drawing of the resultant vector. > Mistake found at 41'53", 305.5 degrees should be -305.5 degrees
Lesson 10.1 Notes w/Student Companion YouTube Video > Mistake found @19'39", Example 3a, matrix should be [[-3+6, 5+5], [2+-8, 0+0.2]], not [[-3+6, 5+5], [2+0, 0+0.2]]. Then @20'03", the matrix should be [[3, 10], [-6, 0.2]] > Mistake found @21'16", Example 3b, matrix should be [[9, 0], [-10, 0.2]], not [[9, 0], [-8, 0.2]]
