When we have functions with more than one variable, we can find partial derivatives by holding all the variables but one constant. z 100 10 y 10 x (eff sub ecks) Note: is also written as
would give you the slope of the tangent in the plane y=0 or in any plane with constant y. z 100 10 y 10 x In other words, how is changing one variable going to change the value of the function?
Mixed variables are also possible: Both answers are the same! p
