New Question

[Confused312]

Thanks soo much you helped a lot with my other question... I have one more that stumped me and ill be done!!

sec ^2 x + csc ^ 2 x - ( tan ^2 x + cot^ 2 x)

I got 0 as an answer is that right?

Are the instructions for this one to "simplify"?

I don't get a value of "2" for the simplification. I used the Pythagorean Identities (similar to "sin²(x) + cos²(x) = 1", but the ones for tangent, cotangent, secant, and cosecent). Try using those to simplify.
