Question

Evaluate : tan 45°+sin 30°-csc30°

Answer 1

tan 45+sin30 -csc 30= 1+1/2-2= 2+1-4/2=-1/2

Answer 2

Answer:

tan45° + sin 30° - cosec 30°

1 + 1/2-2

1×2/1×2+ 1/2 -2

2/2+1/2 -2

3/2 -2

3/2 -2×2/1×2

3/2- 4/2

-1/2 [ If we consider third term as cosec 30°]

tan 45° + sin 30° - cos 30 °

1+1/2-√3/2

1+ 1-√3/2

1×2/1×2 - 1-√3/2

2/2+1-√3/2

2+1-√3/2

3-√3/2 [ if we consider third term as cos 30°]
