Why is the video like that I can't even understand anything cus I can't see anything I only hear the voice 

<h2>Measurement of Price Elasticity of Supply</h2>
<h3>1) The Point Method:</h3>
<p>a) Applicable to a supply schedule:</p>
<p>\(E_s = \cfrac{\Delta Q}{\Delta P} \times \cfrac{P}{Q}\)</p>
<p>Note: There is no minus (\(-\)) sign in the formula unlike that of price elasticity of demand.</p>
<p>b) Applicable to a supply function:</p>
<p>i) \(E_s = \cfrac{\delta Q}{\delta P} \times \cfrac{P}{Q}\) (for a supply function with one independent variable).</p>
<p>ii) \(E_s = \cfrac{\partial Q}{\partial P} \times \cfrac{P}{Q}\) (for a supply function with two or more independent variables).</p>
<h3>2) The Arc Method:</h3>
<p>\(E_s = \cfrac{\Delta Q}{\Delta P} \times \cfrac{P_1 + P_2}{Q_1 + Q_2}\)</p>

Measurement of Price Elasticity of Supply

Economics studies social behavior guiding the allocation of scarce resources to meet the unlimited needs and desires of the individual members of a given society, and for the production of goods and services, growth of production and welfare over time, and a great variety of other complex issues of vital concern to society.
