I think ace meant
\[ \sin^2 x + \cos^2 x = 1\]
I would first find a common denominator. Can you do that?

@aceace @phi i would get this for the right side : \[\huge =\frac{ 2 }{ 1\sin^2x }\]

After simplify you'll get the result = 2/ cos²x

1/sinx+1=sinx1/sin^2x1
=1sinx/1sin^2x
=1sinx/cos^2x
1/sinx1=sinx+1/sin^2x1
=1sinx/1sin^2x
=1sinx/cos^2x
=(1sinx(1sinx)/cos^2x
=2/cos^x
