If you will show your work here..then it will be easier to tell
Hey, I am really rusty on my multivariable calc stuff and cannot seem to get the right answer to...
with respect to x and with respect to y.
Help? I don't know what techniques to imply. I just went ahead and did it as if it were just a single variable function since I only needed it with respect to x and also with respect to y.
You want and
Then when when calculating remember that
As long as this isn't an implicit function, you treat the other variables as constants while deriving for one.
Also remember the derivatives rules for fractions
And the derivative of tangent
That's all you need to know.
