Relatively inelastic supply: This is when the E s formula gives a result between zero and one, meaning that when there is a change in price, the percentage change in supply is lower than the percentage change in price. For example, if a product costs $1 and then increases to $1.10 the increase in price is 10% and therefore the change in supply ...
Total revenue, the product price times the quantity of the product demanded, can be represented at an initial point by a rectangle with corners at the following four points on the demand graph: price (P 1), quantity demanded (Q 1), point A on the demand curve, and the origin (the intersection of the price axis and the quantity axis).
When the price elasticity of demand for a good is perfectly inelastic (E d = 0), changes in the price do not affect the quantity demanded for the good; raising prices will always cause total revenue to increase. Goods necessary to survival can be classified here; a rational person will be willing to pay anything for a good if the alternative is ...
Graph of a tax wedge, showing consumer and producer incidence. The tax wedge is the deviation from the equilibrium price and quantity (and , respectively) as a result of the taxation of a good.

The deadweight loss would be zero when either demand or supply is perfectly inelastic. The third graph in the page you mentioned is what happens when demand is inelastic. The white triangle of deadweight loss is small, and if the demand were completely inelastic (i.e. a vertical line,) it would be nonexistent.
If price elasticity of demand is calculated to be less than 1, the good is said to be inelastic. An inelastic good will respond less than proportionally to a change in price; for example, a price increase of 40% that results in a decrease in demand of 10%. Goods that are inelastic often have at least one of the following characteristics:
If the elasticity's absolute value is between zero and 1, demand is said to be inelastic; if it equals 1, demand is "unitary elastic"; if it is greater than 1, demand is elastic. A small value--- inelastic demand--- implies that changes in price have little influence on demand.
