Answer 1

Answer:

sin(45

o

+θ)−cos(45

o

−θ)

⇒sin5

o

cosθ+cos45

o

sinθ−cos45

o

cosθ−sin45

o

sinθ

Answer 2

Step-by-step explanation:

{sin45° + Θ } - { cos45° - Θ }

step 1. open the brackets.

.

.

sin45° + Θ - cos45° + Θ

.

.

sin45° = cos45° = (1/√2)

.

.

so,

step 2. put the values of tri. ratio

.

.

= sin45° + Θ - cos45° + Θ

.

= 1/√2 + Θ - 1/√2 + Θ

.

= 2 Θ (ans)
