HP Prime: Unexpected "poly1" after cross product
What does it mean when HP Prime prepends "poly1" to the vector/matrix output of a calculation?
I calculated the following: CROSS([0.01 0 0],[60 0 0])  0.02^2 * 60 + CROSS([0 0 0.02],[0.5 0 0]) Which returns just the following, as expected: [0.62 0.024] However, when I copy this output to the entry field (I forget what HP calls this) to do a second calculation, my HP Prime prepends "poly1," to it, so I get: poly1[0.62 0.024] I haven't been able to figure out what this means or why it shows up, only that I have to manually delete it before doing the next calculation to get the expected answer. Thank you!
