SUMMARY

The discussion focuses on calculating the partial derivatives of the function f(x,y,z) = 50 - 14x + 3y² - 2xy(e^z). The correct approach involves treating the variables not being differentiated as constants. The partial derivative with respect to x is ∂f/∂x = -14 - 2y(e^z), while the partial derivatives with respect to y and z follow similar principles. The participants clarify that for ∂f/∂y, x and z are treated as constants, and for ∂f/∂z, x and y are treated as constants.

PREREQUISITES

Homework Statement



I need to find the partial derivitives of f(x,y,z)=50-14x+3y^2-2xy (e^z)

Homework Equations





The Attempt at a Solution


i think the x-partial would be -14+2ye^z+2xye^z... but I'm not sure and I'm confused of how to find the others!

f(x,y,z)=50-14x+3y2-2xyez

simply when taking the partial derivative w.r.t. to a variable, you treat the rest as constants.

so for ∂f/∂x, we would treat y and z as constants and differentiate normally.

∂f/∂x=∂/∂x(50)-∂/∂x(14x)+∂/∂x(3y2)-∂/∂x(2xyez)


How did you get your answer though?


So for ∂f/∂z, treat x and y as constants. It is similar for ∂f/∂y.
