In this section we solve problems on partial derivatives which have direct impact on Industrial areas.

Production function and marginal productivities of two variables

### (i) Production function:

Production P of a firm depends upon several economic factors like capital (K), labour (L), raw materials (R),machinery (M) etcŌĆ” Thus P = f(K,L,R,M,ŌĆ”) is known as production function. If P depends only on labour (L) and capital (K), then we write P=f(L,K).

### (ii) Marginal productivities:

Let P = f(L,K) be a production function. Then ŌłéP/ŌłéL is called the Marginal productivity of labour and ŌłéP/ŌłéL is called the Marginal productivity of capital.

EulerŌĆÖs theorem for homogeneous production function P(L,K) of degree 1 states that Tags : Applications of partial derivatives , 11th Business Mathematics and Statistics(EMS) : Chapter 6 : Applications of Differentiation
