1. Utility: In mathematics, utility refers to a measure of satisfaction or usefulness that an individual derives from consuming a certain quantity of goods or services. It is usually denoted by the letter "U" and can be represented mathematically in utility functions, such as U(x, y), where x and y are the quantities of different goods consumed.

2. Util: Util, short for utility unit, is a mathematical unit used to represent the level of satisfaction or utility that an individual derives from consuming a certain amount of goods or services. It is a subjective measure and varies from person to person.

3. Iso cost: In mathematical economics, an iso cost line represents all the combinations of two inputs (such as labor and capital) that can be purchased at a given cost or expenditure level. It shows the various combinations of inputs that can be chosen while keeping the total cost constant.

4. Indifference curve: An indifference curve is a graphical representation used in economics to show the different combinations of two goods that provide the same level of satisfaction or utility to an individual. It represents the preferences of an individual who is indifferent between the different combinations, implying that they view the combinations as equally desirable.

5. Budget line: In economics, a budget line (also known as the budget constraint or income constraint) represents the different combinations of two goods that can be purchased by an individual or a consumer given their income and the prices of the goods. It shows the maximum quantities of one good that can be purchased for a given quantity of another good, given the budget constraint.
