Question

can you please solve and give correct answer ​

Answer 1

Step-by-step explanation:

1-cos+sin/ 1+sin =2sin/ 1+cos+sin

=1-cos+sin/ 1+sin × 1+cos-sin/1+cos-sin

= (1)²-(cos+sin)²/1+sin+cos+sincos-sin-sin²

= 1-(sin²+cos²-2sincos)/cos²+1-sin²+sincos

= 1-(1-2sincos)/cos²+cos+sincos

= 1-1+2sincos/cos(1+cos+sin)

= 2sincos/cos(1+cos+sin)

= 2sin/1+cos+sin
