Where does sin2x+cos2x=1 come from to begin with (think Unit Circle!). You should be referring to Unit Circle ratios and the Pythagorean Theorem in your explanation.
An identity is any proven facts and formulas tht are always true. We have the unit circle in which we have our magic 5 pair. We get sin2x +cos2x =1. If we get any value on the unit circle like radical 3/2,1/2.if we do the math we end up getting the overall answer to equal 1

If I had to describe trigonometry in THREE words, they would be…
