application of integration in economics and commerce

}\], Making the change \(z = \sqrt{Q},\) we get the quadratic equation \({z^2} + z – 30 = 0,\) which has the roots \(z = 5,\) and \(z = -6.\) The positive solution \(z = 5\) gives the equilibrium point \({Q_0} = {z^2} = 25.\) The price at this point is \({P_0} = 25.\). {\left( {2{x^2} – \frac{{3{x^4}}}{4} – \frac{{{x^3}}}{3}} \right)} \right|_0^1 }={ \frac{2}{5}\left( {2 – \frac{3}{4} – \frac{1}{3}} \right) }={ \frac{{11}}{{30}} }\approx{ 0.37}\], We compute the Gini coefficient using the formula, \[G = 2\int\limits_0^1 {\left[ {x – L\left( x \right)} \right]dx} .\], \[{G = 2\int\limits_0^1 {\left[ {x – \left( {1 – \sqrt {1 – {x^2}} } \right)} \right]dx} }={ 2\int\limits_0^1 {\left( {x – 1} \right)dx} + 2\int\limits_0^1 {\sqrt {1 – {x^2}} dx} }={ {I_1} + {I_2}.

We can use this same method to obtain the total cost function given a firm’s marginal cost function. }\], When \(x = 0,\) \(t = 0,\) and when \(x = 1,\) \(t = \large{\frac{\pi }{2}}\normalsize.\) So, \[{{I_2} = 2\int\limits_0^1 {\sqrt {1 – {x^2}} dx} }={ 2\int\limits_0^{\frac{\pi }{2}} {\sqrt {1 – {{\sin }^2}t} \cos tdt} }={ 2\int\limits_0^{\frac{\pi }{2}} {{{\cos }^2}tdt} }={ \int\limits_0^{\frac{\pi }{2}} {\left( {1 + \cos 2t} \right)dt} }={ \left. Department of Economic Affairs, Commerce and Industry (DEACI) L.G. Economy tutorial 03. {dv = dt}\\ Consumer surplus is represented by the area under the demand curve \(P = D\left( Q \right)\) and above the horizontal line \(P = {P_0}\) at the level of the market price. First we find the point of market equilibrium: \[{D\left( Q \right) = S\left( Q \right),}\;\; \Rightarrow {{\left( {Q – 2a} \right)^2} = {Q^2},}\;\; \Rightarrow {\left| {Q – 2a} \right| = \left| Q \right|. Substituting \(L\left( x \right) = {x^3}\) and evaluating the integral, we find: \[{G = 2\int\limits_0^1 {\left[ {x – L\left( x \right)} \right]dx} }={ 2\int\limits_0^1 {\left( {x – {x^3}} \right)dx} }={ 2\left. Learn about the various ways in which we can use integral calculus to study functions and solve real-world problems. {\left( {\frac{{{x^2}}}{2} – \frac{{{x^{p + 1}}}}{{p + 1}}} \right)} \right|_0^1 }={ 2\left( {\frac{1}{2} – \frac{1}{{p + 1}}} \right) }={ 1 – \frac{2}{{p + 1}}. In all sectors of the tourism industry the influence of ICT and Internet can be noticed through internal re-organization, relationships with partners and the way it relates … Examples of Integral Applications, featuring uses in economics. {\left( {500Q – \frac{{25{Q^2}}}{2}} \right)} \right|_0^{20} }={ 10000 – 5000 }={ 5000. Generally, the demand function \(P = D\left( Q \right)\) is decreasing, because consumers are likely to buy more of a product at lower prices. Application of Integration in Economics and Commerce. }\], To calculate the capital accumulation, we use the formula, \[{K = \int\limits_a^b {I\left( t \right)dt} }={ \int\limits_1^5 {\ln tdt} . It is possible to find out consumer’s surplus and producer’s surplus from the demand and supply function. Applications of calculus in commerce and economics ii 1. But it is uncertain that there is interaction between the common growth and the VAR model can be used to explain that. Thus the economic integration refers to an arrangement whereby two or more countries combine into a larger economic region through the removal of discontinuities and discriminations existing along national frontiers, while following a common tariff and trade policies against the countries outside the group. Integration helps us to find out the total cost function and total revenue function from the marginal cost. }\], Similarly we determine the producer surplus \(PS:\), \[{PS = \int\limits_0^{{Q_0}} {\left[ {{P_0} – S\left( Q \right)} \right]dQ} }={ \int\limits_0^a {\left( {{a^2} – {Q^2}} \right)dQ} }={ \left. economic consequences of access to e-commerce trading. math videos 2. x R AR Average revenue Marginal Revenue = dx dR Marginal Average Revenue = dx dAR www.mathews.co.in. {\left( {5Q – \frac{{2{Q^{\frac{3}{2}}}}}{3}} \right)} \right|_0^{25} }={ 125 – \frac{{250}}{3} }\approx{ 41.7}\]. {\left( {{a^2}Q – \frac{{{Q^3}}}{3}} \right)} \right|_0^a }={ {a^3} – \frac{{{a^3}}}{3} }={ \frac{{2{a^3}}}{3}.}\]. The total capital accumulation \(K\) during the time interval \(\left[ {a,b} \right]\) can be estimated by the formula, \[K = \int\limits_a^b {I\left( t \right)dt} .\]. Lesson 22: Applications to Business and Economics 1. Trades in different countries have certain restrictions as well as some tariffs, which can be issued in a very discriminatory manner for sure. To solve the second integral, we make the substitution: \[{x = \sin t,\;\;}\kern0pt{dx = \cos tdt. 2019 words (8 pages) Essay. \end{array}} \right] }={ t\ln t – \int {\cancel{t}\frac{{dt}}{\cancel{t}}} }={ t\ln t – \int {dt} }={ t\ln t – t.}\], \[{K = \left. {u = \ln t}\\ It is mandatory to procure user consent prior to running these cookies on your website.
