The derivative of y = xln(x) with respect to x is dy/dx = ln(x) 1 This result can be obtained by using the product rule and the wellknown results d(ln(x))/dx = 1/x and dx/dx = 1A constant and the derivative of x2 with respect to x is 2x For the second part x2 is treated as a constant and the derivative of y3 with respect to is 3 2 Exercise 1 Find ∂z ∂x and ∂z ∂y for each of the following functions (Click on the green letters for solutions) (a) z = x2y4, (b) z = (x4 x2)y3, (c) z = y12 sin(x)
Derivative of ln(x^2 y^2) with respect to y
Derivative of ln(x^2 y^2) with respect to y-Solution 1) We are taking the natural logarithm of x 2 5, so f (x) = x 2 5 Taking the derivative of that gives us f' (x) = 2x 2) Now, let's take f (x), f' (x), and plug them into the derivative rule d ⁄ dx ln f (x) = f' (x) ⁄ f (x) = 2x ⁄ x2 5 3) The final answer is d⁄dx ln (x2 5) = 2x⁄x2 5Derivative Here, n = 4 d/dx

Solution To find the xderivative, we consider y to be constant and apply the onevariable Chain Rule formula d dx (f10) = 10f9 df dx from Section 28 We obtain ∂ ∂x (x2y3 sinx)10 = 10(x2y3 sinx)9 ∂ ∂x (x2y3 sinx) = 10(x2y3 sinx)9(2xy3 cosx) Similarly, we find the yderivative by treating x as a constant and using the sameFxy = ∂fx / ∂y, where f (x) is the first derivative with respect to x fyx = ∂fy / ∂x, where f (y) is the first partial derivative with respect to y However, an online Directional Derivative Calculator determines the directional derivative and gradient of a function at a given point of a vector Example Calculate the first, second
