Vertify the identities, clearly show each step (vertify one side that they are equal to each other)
sec^2+csc^2=sec^2+csc^2

Please check your question.
The lefthand side is already identical to the righthand side.
If the question was
sec^2+csc^2=sec^2 csc^2
then you only have to add the lefthand side together:
sec^2+csc^2
=(sin^2+cos^2)/(cos^2 sin^2)
=1/(cos^2 sin^2)
=sec^2 csc^2
