Question

sin30/cos45 + cot45/cosec30 - sin60/tan45 - cos30/sin90​

Answer 1

Step-by-step explanation:

Answer : root 2 + 1 / 2

sin 30 = 1/2

cos 45 = 1/root 2

cot 45 = 1

cosec 30 = 2

sin 60 = root3/2

tan 45 = 1

cos 30 = root3/2

sin 90 = 1

Substituting values , we get ;

1/2 by 1/root 2 + 1 by 2 - root 3/2 by 1 - root3/2 by 1

= root2 + 1 by 2

Answer 2

Answer:

-0.52

Step-by-step explanation:

sin30/cos45 + cot45/cosec30 - sin60/tan45 - cos30/sin90

= 1/2/1/$\sqrt{2}$ + 1/2 - $\sqrt{3}$/2/1 - $\sqrt{3}$/2/1

= $\sqrt{2}$/2 + 1/2 - $\sqrt{3}$/2 - $\sqrt{3}$/2

= ($\sqrt{2}$+1-$\sqrt{3}$-$\sqrt{3}$)/2

= -1.05/2

= -0.52
