Question

1. Evaluate the following:
(1) sin 60° cos 30° + sin 30° cos 60° (ii) 2 tan- 45° + cos? 30°-sin-60°
cos 45º
sin 30° + tan 45º - cosec 60°
sec 30° + cosec 30
sec 30° + cos 60° + cot 45°
5 cos? 60° + 4 sec 30° - tanº 45°
(v)
sin? 30° + cos 30°
Cose the correct option and justify your choice :
2 tan 30°
1 + tan30°
(A) sin 60°
1- tan² 45°
(
DO
1 + tan 45º
the third
2. Choose the correct
(1)
m
.
(D) sin 30
(C) tan 60°
(B) cos 60°
(O) sin 45​
