You did just fine and your second derivative is correct, if you meant (6y^2 - 4x^2)/(9y^3)
except they took it a bit further.

Thank you Dr. Bob! :)I had that but it seemed too simple to be true. I didn't have my text to verify.
Thank you.
Positive and negative- in the sense things should cancel and charges should inc. and dec.
What is your charge for Au? There has to be a positive and negative- check your equations- that answers then may not apply.
9pi/12 should be converted into degrees. The value of pi is 180 so all you do is 180 times 9 divided by 12 and then take the cosine of that value.
The first rxn is reduction. Au went from +3 to 0 so higher to lower number (became more -ve) Na is oxidized. went form 0 to +3

Okay thanks for feedback. Should I have given, I guess, real life examples of issues today? Also, what other sort of higher authority should I have written about? Something less than government, like maybe the school's principal, or boss at work? Thanks.

Okay thank you so much for your feedback sir.
