13.3 Partial derivatives For an animation of this concept visit
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 Note: is also written as (eff sub ecks)
Notation for First Partial Derivatives
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?

Section 13.3 Partial Derivatives. To find you consider y constant and differentiate with respect to x. Similarly, to find you hold x constant and differentiate.
Derivatives - Equation of the Tangent Line Now that we can find the slope of the tangent line of a function at a given point, we need to find the equation.
