f. tan ß where ß is a positive angle in quadrant II if sin ß = 7/10

g. sin ß where ß is a negative angle in quadrant IV and cos ß = 4/5

h. sec ß where ß is a positive angle in quadrant III if tan ß = 6/7

i. csc ß where ß is a positive angle in quadrant III if cos ß = -7/11

j. tan ß if ß is in quadrant II and ß = arcsin 3/8.

k. sin ß if ß is in quadrant III and ß = arctan ß = 2/3

2. Solve the following quadratic equations: (use factoring or the quadratic formula)

a. x2 -4x + 2 = 0

b. x2 -5x + 6 = 0

c. x2 +5x + 6 = 0

d. x2 -4x + 10 = 0
