Example 1 In the above Table, left column, it is found that cos30° = √3/2Since sin30° = 1/2, we may use sin 2 (30°) cos 2 (30°) = 1 to solve for cos30° Solution Substituting for sin(30°), we get (1/2) 2 cos 2 (30°) =1, or, cos 2 (30°) = 3/4, or, cos(30°) =√3/2 Example 2 In the above Table, middle column, it is found that tan30° =√3/3√ 3/2 (iii) 5 marks Say the line connecting (3,0)and (1,2h)has equation y=mxc Then we have 3mc=0andmc=2hgivingm=−handc=3hSothelinehasequation y=h(3−x) Thiswillbetangentialtox2y2=4when x 2h(3−x)2=4 hasarepeatedroot(ie azerodiscriminant) Theequationrearrangesto h 21 x −6h2x 9h2−4 =0 Thediscriminantiszerowhen 36h4=4 hCos √3 2 sin 4 5 6 If ,find tan Use a ratio identity to find tan if 7 and 8 and Use a ratio identity to find cot if 9 and sin 2 and cos 3√13 cos 12 13 sin 5 13 sin 2 √5 cos 1 √5 cos 4 5 sin 3 5 cot b (b 0) Multiply (sin 2)(sin 5) Solution We multiply these two expressions in the same way we would multiply (x 2)(x 5) FO IL
