Answer 1

Answer:

OPTION 4

Step-by-step explanation:

Let theta be x for benefit .

tan x = a/b

⇒ sin x / cos x = a / b

⇒ b sin x / a cos x = 1 / 1

Now by componendo and dividendo :

⇒ ( b sin x + a cos x ) / ( b sin x - a cos x ) = ( 1 + 1 ) / ( 1 - 1 )

By Invertendo :

⇒ ( b sin x - a cos x ) / ( b sin x + a cos x ) = 0 / 2

= 0

Hence the answer is 0.
