Question

W
cos (90° - 0) 1+ sin (90° - 0)
-= 2 coseco
1+ sin (90° - 0)' cos (90° - 0) --co​

Answer 1

1. cos (90-0)/1+sin (90-0) + 1+ sin(90-0)/cos(90-0)
2. Sino/1+coso. + 1+coso/Sino
3. take LCM

sin^20 + (1+cos0)^2 /(1+cos0)sin0

sin^20 +1+cos^20+2cos0/(1+cos0)sin0

2+2cos0/(1+cos0)sin0

2(1+cos0)/(1+cos0)sin0

2/sin0

2cosec 0

I HOPE IT IS HELPFUL
