Partial derivative of log(x^2+y^2)
Partial derivative of log(x^2+y^2)- I have a function g as a function of x;Then I'll find the second derivative of F with respect to X And with respect to X Again, to do this, I will in the partial derivative of F with respect to X, hold Y constant and differentiate with respect to X Again, so I get 12 X squared y squared minus six X Y Yeah I'll also find the second partial derivative of F With respect to X

Section73 Partial Differentiation ¶ 🔗 The derivative of a function of a single variable tells us how quickly the value of the function changes as the value of the independent variable changes Intuitively, it tells us how "steep" the graph of the function is We might wonder if there is a similar idea for graphs of functions of twoFind partial derivative of the following 1) f(x, y) = 3x cos(x) cos(y) df'/dx=?@f @y = 4 (b) f(x;y) = xy3 x 2y 2;
F' x = y 3 cos (x) 2x tan (y) Likewise with respect to y we turn the "x" into a "k" f (x, y) = y 3 sin ( k) k 2 tan (y) f' y = 3y 2 sin (k) k 2 sec 2 (y) f' y = 3y 2 sin (x) x 2 sec 2 (y) But only do this if you have trouble remembering, as it is a little extra work $$\frac{\partial}{\partial x} \ln(x^2y^2)$$ now if this was just $\frac{d}{dx}\ln(x^2)$ we would get $\frac{2x}{x^2}$ So I feel we would get$$\frac{\partial}{\partial x} \ln(x^2y^2)=\frac{2x}{x^2y^2}$$Please Subscribe here, thank you!!!
The partial derivative of a function of multiple variables is the instantaneous rate of change or slope of the function in one of the coordinate directions Computationally, partial differentiation works the same way as singlevariable differentiation with all other variables treated as constant The partial derivative of a function f (x, y) f(x,y) f (x, y) in the x x xdirection can be//googl/JQ8NysPartial Derivative of f(x, y) = xy/(x^2 y^2) with Quotient Rule@f @x = 3;
