Question

solve [2 (i),(ii)] 3 (i),(ii)

Answer 1

2 (1ans 3/8) 2(2ans 1/2) 3(1ans 1-2√3 ) 3(2ans1/3)

Answer 2

2 i) 4/3sin²60 + cos²60 - sin²45
= (4/3)(3/4) + 1/4 - 1/2
= 1 + 1/4 - 1/2
= 3/4

ii) -(3/4)(1/3) + 5(4/3) + (1/4)(1/3) - 2(3/4)
= -1/4 + 20/3 + 1/12 - 3/2
= 81/12 - 7/4
= 27/4 - 7/4
= 20/4
= 5

3 i) (2)(√3/2) - (3)(2)
= √3 - 6

ii) (2/3)(1/2) +2(0) -4(1/4) - (3/2)(4/3) +3
= 1/3 + 0 - 1 - 2 + 3
= 1/3


hope it helps you
