[1+(cos x /sin x)+(1/sin x)][1+(sin x/cos x)-(1/cos x)]

[1+{(cos x +1)/sin x}]*[1+{sin x-1)/cos x}]

[(sin x+ cos x+1)/sin x]*[(cos x+sin x-1)/cos x]

[(sinx +cosx)square -1 square]/sinx cosx

[sin^2x +cos^2x-2 sinx cosx -1]/sinx cosx

[1-2sinx cosx-1]/sinx cos x

-2 sinx cosx/sinx cosx

-2

Answer is -2
