## How do you find the limit of a partial derivative?

The partial derivative ∂f∂x(0,0) is the slope of the red line. The partial derivative at (0,0) must be computed using the limit definition because f is defined in a piecewise fashion around the origin: f(x,y)=(x3+x4−y3)/(x2+y2) except that f(0,0)=0.

## What are the limitations of Cobb and Douglas production function?

Since, the Cobb-Douglas (CD) function has been (and is still) abundantly used by economists because it has the advantage of algebraic tractability and of providing a fairly good approximation of the production process. Its main limitation is to impose an arbitrary level for substitution possibilities between inputs.

**What does Alpha mean in Cobb Douglas?**

Alpha is simply the percentage of capital I use in my production process, whilst beta is the percentage of labour used.

### What does it mean if a partial derivative is 0?

If a function of n variables is constant on some open neighborhood defined by an inequality of the form |v −a| < h, where h > 0, then it follows that all the partial derivatives of f are zero. Since x was arbitrary this means that f is constant on U.

### What is partial limit?

From Encyclopedia of Mathematics. of a given sequence. The limit of some subsequence. Any sequence of numbers (and also any sequence of points in a finite-dimensional Euclidean space) has at least one partial limit (finite or infinite).

**What are the advantages of Cobb-Douglas production function?**

These advantages are due to the fact that it can handle multiple inputs in its generalised form. Even in the face of imperfections in the market it does not introduce distortions of its own. Unconstrained CD-function further increases its potentialities to handle different scales of production.

#### How do you know if a function is Cobb-Douglas?

A Cobb-Douglas Function takes the form of Q=KαLβ where Q=output, K=capital, L=labour, and alpha and beta are used to represent input shares of capital and labour respectively. In this form we have used CD as a production function.

#### How do you calculate MRTS?

How to Calculate MRTS?

- K = Capital.
- L = Labor.
- MP = Marginal products of each input.
- (∆K÷∆L) = Amount of capital that can be reduced when labour is increased (typically by one unit)
