1. Find the amplitude, if it exists, and the period of y=tan 1/4È

Answer: No limits in amplitude, y=tanÈ/4 period is 4pi

2.Solve x = Arctan(-sqrt3)
Work: Pythagorean theorem: sqrt(1^2+3)= sqrt4=2 in length. Triangle is 1, sqrt 3,2

Answer: -60°

3. In triangleABC, A = 35°, a = 43, and c = 20. Determine whether triangle ABC has no solution, one solution, or two solutions. Then solve the triangle. Round to the nearest tenth

Answer: One solution; 57.8
