Here is the solution for question 9(ii): Step 1: Substitute the known values of the trigonometric ratios. We know that: 30^ = (1)/(2) 60^ = sqrt(3) 60^ = (1)/(2) 30^ = (2)/(sqrt(3)) Step 2: Substitute these values into the given expression. 2 ^2 30^ 60^ - 3 ^2 60^ ^2 30^ = 2 ((1)/(2))^2 (sqrt(3)) - 3 ((1)/(2))^2 ((2)/(sqrt(3)))^2 Step 3: Perform the squaring operations. = 2 ((1)/(4)) (sqrt(3)) - 3 ((1)/(4)) ((4)/(3)) Step 4: Multiply the terms in each part of the expression. = 2sqrt(3)4 - (3 × 1 × 4)/(4 × 3) = sqrt(3)2 - (12)/(12) = sqrt(3)2 - 1 Step 5: Combine the terms to get the final answer. = sqrt(3)2 - 1 That's 2 down. 3 left today — send the next one.
