Could someone give me some guidance on how to simplify this expression:

(tan(y) + cot(y)) / csc2(y)

That 2 is a square. Thanks for your help.

tan = 1/cot
csc = 1/sin
tan = sin/cos (i think)
sin2 + cos2 = 1

Use those and go from there.

The answer is tan(y)

I will give some intermediate steps.

The rest is up to you. (I am not bothering to write the argument y)

...

sin^2(sin/cos+cos/sin)

...

then

sin(sin^2/cos + cos^2/cos)

...

=
tan(y)
