PARTIAL DERIVATIVES AND THEIR APPLICATIONS 4 aaaaa 41 INTRODUCTON FUNCTIONS OF SEVERAL VARIABLES So far, we had discussed functions of a single real variable defined by y = f(x)Here in this chapter, we extend the concept of functions of two or more variablesThe partial derivative of y = f(x) with respect to x is written as f x x,y , or z x y y y y e y y e y y f x y 1 1 ln 1 3 1 3 2 3 2 2 Example 5 Find f z if , 35 1 yz2 z f y zx w means we act as if z is our only variable, so we'll act as if all the other variables (x, y and w) I am new to partial derivatives and they seem pretty easy, but I am having trouble with this one $$\frac{\partial}{\partial x} \ln(x^2y^2)$$ now if this was just $\frac{d}{dx}\ln(x^2)$ we would get $\frac{2x}{x^2}$ So I feel we would get$$\frac{\partial}{\partial x} \ln(x^2y^2)=\frac{2x}{x^2y^2}$$

Thus, we have 1 / (xln(e)) = 1 / (x⋅1) = 1 / x As stated in our facts, we get that the derivative of ln( x ) is 1/ x , and we see just how useful this formula can be01 Recall ordinary derivatives If y is a function of x then dy dx is the derivative meaning the gradient (slope of the graph) or the rate of change withDerivatives of logarithmic functions are mainly based on the chain ruleHowever, we can generalize it for any differentiable function with a logarithmic function The differentiation of log is only under the base e, e, e, but we can differentiate under other bases, too
