Short run costs are the cost over a period during which some of production factors (usually capital, equipment and management) are fixed The long –run term costs are the costs over a period long enough to permit the change of all factors of production. In long run, all factors become variable. Both in short run and in long run, total cost is multivariate function. That is total cost is determined by many factors. Symbolically we may write the long-run function as
C=f(X, T, ,K)

And short run cost function as
C=f(X, T, ,K)

WHERE
C=TOTAL COST

X=output
T=technology
K=PRICE OF FACTORS=FIXED FACTORS(S)
Cost is the function of output c=f(X)
