 Nov 3 awarded Student Apr 27 accepted Multivariable Chain Rule Apr 27 comment Multivariable Chain Rule I Took the derivative of both sides, and obtained the following: $G'(x^2+y^2,x+y)\cdot\begin{bmatrix} 2x&2y \\ 1&1 \end{bmatrix}=\begin{bmatrix} 7&3 \\ 1&5 \end{bmatrix}$ @EricTowers, but i have no idea how i should do next Apr 27 asked Multivariable Chain Rule Feb 4 awarded Informed Feb 3 comment Where $a$ and $b$ are both constants, find the values of $a$ and $b$ great!! but just for curiosity, what if instead of using using -1/3 for the value of x, you use a different number such as 3? would it still be possible to find that a=2 and that b=3? Feb 3 awarded Scholar Feb 3 accepted Where $a$ and $b$ are both constants, find the values of $a$ and $b$ Feb 3 comment Where $a$ and $b$ are both constants, find the values of $a$ and $b$ well maybe there is, I checked and double checked my textbook and many friends are also having problems with this particular exercise, maybe there is a mistake in the textbook. Thanks! Feb 3 comment Where $a$ and $b$ are both constants, find the values of $a$ and $b$ yes, the denominators are correct, thanks for your help!
