Question: 1. Find a b. a = 5i + 7j, b = -4i + 3j a b c 1 d 41 2. Find all polar coordinates



1. Find a b.
a = 5i + 7j, b = -4i + 3j
| a | |
| b | |
| c | 1 |
| d | 41 |
2. Find all polar coordinates of point P where P = (6, - /5)
| a | (6,- /5 + 2n) or (-6,- /5+ 2n) |
| b | (6,- /5+ 2n) or (-6,- /5+ (2n + 1)) |
| c | (6,- /5+ (2n + 1)) or (-6,- /5+ 2n) |
| d | (6,- /5+ 2n) or (6,- /5+ (2n + 1)) |
3. Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 5 + 4 cos
| a | x-axis only |
| b | y-axis only |
| c | No symmetry |
| d | Origin only |
3. Use graphs and tables to find the limit and identify any vertical asymptotes of the function.
