sinx / 1+cosx + 1+cosx / sinx = 2cscx
sin²x + (1+cosx)² / sinx (1 + cosx) = 2cscx
sin²x + 1 + 2cosx + cos²x / sinx (1+cosx) = 2cscx
1 + 1 + 2cosx / sinx (1 + cosx) = 2cscx
2 + 2cosx / sinx (1 + cosx) = 2cscx
2 (1 + cosx) / sinx (1 + cosx) = 2cscx
2 ( 1 / sinx ) = 2csc x
2csc x = 2csc x
sin²x + (1+cosx)² / sinx (1 + cosx) = 2cscx
sin²x + 1 + 2cosx + cos²x / sinx (1+cosx) = 2cscx
1 + 1 + 2cosx / sinx (1 + cosx) = 2cscx
2 + 2cosx / sinx (1 + cosx) = 2cscx
2 (1 + cosx) / sinx (1 + cosx) = 2cscx
2 ( 1 / sinx ) = 2csc x
2csc x = 2csc x
