1. ## Isoquant

Hi,

I'm trying to understand how we can have capital and labour on the two axes and then have a curve drawn on the same graph representing an output level? Trying to understand the mathematical explanation for this. Don't you usually need to have one variable as a function of the other? Isoquants seem like random lines?

it's a contour curve.

The curve represents points of a particular value of the function, i.e. $f(capital, ~labor) = Q$ for some $Q$

Ah thanks for that.

"Isoquant" is an interesting word. "Iso", "same", and "quant" from "quantity". Similar to "isobar", a line of constant barometric pressure.
