LHS= (SinA +1/CosA)² +(CosA+ 1/SinA)²      
      =((SinACosA +1)/CosA)²+((SinACosA +1)/SinA)²       
     =(SinACosA +1)
²/Cos²A +(SinACosA+1)²/Sin²A     
     =(SinACosA +1)
² {1/Cos²A +1/Sin²A}    
     =(SinACosA +1)
² {Sin²A +Cos²A /Sin² A Cos² A}     
      =(SinACosA +1)
² {1/Sin² A Cos² A)      
       =( SinA Cos A/SinA Cos A +1/SinA Cos A)
²      
        =(1+CosecA.SecA)
²    
         =RHS
Hence proved

roh4: lol
roh4: i am not understanding
