Question

sin 30° + tan 45º – cosec 60°
sec 30° + cos 60° + cot 45°
​

Answer 1

sin 30°= 1/2

tan 45°=1

cosec 60°=2/√3

sec30°=2/√3

cos 60°1/2

cot 45°=1

by substitution this values,

sin 30°+tan45°- cosec 60°

= 1/2+1-2/√3

1/2+2/2-2/√3

=3/2-2/√3

sec 30°+cos 60°+cot 45°

=2/√3+1/2+1

3/2+2/√3

Answer 2

Step-by-step explanation:

LHS=

sin30° + tan45° - cosec60°

= sin(90° - 60°) + tan(90°- 45°) - cosec(90° - 30°)

= cos60° + cot45° - sec30°

= RHS
