Hello, jman242!
Hope you have a sense of humor.
Look at the "Given" . . .
We were told that:- is equal to . . *facepalm*
Get it?
Watch for this . . .
It turns up in many Implicit Differentiaton problems.
I'm not sure if I just hit my limit for the day regarding Calc, but I may have. I was wondering if someone could take a look at this problem for me. I have the solution in front of me, with most of the steps, but I don't see how to go from the last step to the conclusion.
The problem is stated:
If x^2-xy+y^2=3, find y' and y".
2x-xy'-y+2yy'=0
I just don't see how to go from the
to 18/(x-2y)^3
Is there something that is incredibly obvious that I am missing, or is it just another problem with this book? (I have found a few errors already)
Thank you! Any input would be appreciated.
I will admit I chuckled over what was my confusion. I always love tutoring someone and making them see their own error and then point out I do the same exact mistakes. Thanks Soroban. I wish you could have seen my face when I understood, I know you would have laughed. Cheers, and to more mathemagical humor in the future...
