Answer 1

HEY. FREIND...

sin+cos/sin-cos+sin-cos/sin+cos
sin+cot-cos+sin-cot+cos
sin+sin
2sin

Answer 2

Answer:

1

Step-by-step explanation:

sin + cos / sin - cos + sin - cos/ sin + cos

∴sin²+cos²+sin²-cos²/(sin-cos)²

we know that

sin² + cos² = 1_____1

replacing sin²+ cos² with 1

∴1 + sin²- cos² / (sin-cos)²

sin² + sin² / (sin-cos)²_____(∵ sin² + cos² = 1

                                                   ∴ sin² = 1 - cos² )

2 sin²/ (sin-cos)²

may be it will help to solve further !
