Design and develop a simple application System that determine the most economical quantity to be stocked for each product that a manufacturing company has in its inventory this quantity called economics order quantity (EOQ) is calculated as following 

EOQ = sqrt (2RS/I)

R = total yearly Production Requirement 

S = Set up Cost per order

I = inventory carrying cost per unit 

Note: After the user enter the total year production Requirements (R) its set up cost per oder (S) and inventory carrying cost per unit (I) at text baxes 1,2 & 3 expectively the user should Click button (with a compute caption) before the resulting computed value will be displayed at the text box 4 

Use the Convert.TextString(Math.Eqrt(intNum1)); mathematical function to get the square root value
