HELLO DEAR,


i think something mistake in your questions

write questions is like that:-


cosθ/cosecΘ+1+cosθ/cosecθ-1=2tanθ
 \frac{cos \alpha }{cosec \alpha  + 1}  +  \frac{cos \alpha }{cosec - 1}  \\  \\  =  >  \frac{cos \alpha (cosec \alpha  - 1) + cos \alpha (cosec \alpha  + 1)}{(cosec \alpha   +1 )(cosec \alpha  - 1)}  \\  \\  =  >  \frac{cos \alpha    \times \frac{1}{sin \alpha  } - cos \alpha  +  cos \alpha  \times \frac{1}{sin \alpha } + cos \alpha   }{ {(cosec}^{2} \alpha  - 1) }  \\  \\  =  >  \frac{cot \alpha  - cos \alpha  + cot \alpha  + cos \alpha }{ {cot}^{2} \alpha  }  \\  \\  =  >  \frac{2cot \alpha }{ {cot}^{2}  \alpha }  \\  \\  =  >  \frac{2}{cot \alpha }  \\  \\  =  > 2tan \alpha

I HOPE ITS HELP YOU DEAR,
THANKS
