As the statement of the problem says, there are many different equivalent forms of the given expression. And many of them do not look at all similar.

Here is an equivalent form very different from the one shown by the other tutor.

sin^2(x) sec^2(x) − sin^2(x)

sin^2(x)(sec^2(x)-1)

sin^2(x)(tan^2(x))
