Question

1. Evaluate the following:
th sin 60° cos 30° + sin 30° cos 60°
(ii) 2 tan 45º+cos309-sin 60​

Answer 1

Answer:

2

Explanation:

sin60 cos30+sin30 cos60

√3/2x√3/2+1/2x1/2

1+1

2

Answer 2

i) sin 60° cos 30° + sin 30° cos 60°

root 3/2 × root 3/2 + 1/2 × 1/2

3/4 +1/4

3+1/4

4/4

cancelling both we get=1

ii) 2 tan 45° + cos 30° - sin 60°

2 (1) + root 3/2 - root 3 /2

2 + both root 3/2 cancels

=2
