MHF 4U Advanced Functions: UNIT ASSIGNMENT TRIGONOMETRY. Complete Q&A. UNIT ASSIGNMENT TRIGONOMETRY Question 1 zadc a). Find all solutions for sin (x )=√23 b). If sin (x )=1 3 and sec ( y)=54 , where 0≤ x ≤ π 2 and 0≤ y ≤ π 2 , evaluate the expression s in ⁡(x-y) . Answers a). x=π 3 +2πn , 23π +2πn , where n∈Z b). We know that sin θ=opp hyp , and since we know that sin (x )=1 3 , we can draw a triangle using that information, and we can find the unknown side using the Pythag...
