Identify Integral: Identify the integral to be solved.We need to evaluate the integral of the function 2x from the lower limit of 10 to the upper limit of 13.
Set Up: Set up the integral.The integral we need to solve is ∫10132xdx.
Use Power Rule: Use the power rule for integration.The power rule states that the integral of xn with respect to x is (x(n+1))/(n+1)+C, where C is the constant of integration. In our case, n=1, so the integral of 2xdx is 2×(x(1+1))/(1+1)+C, which simplifies to x2+C.
Calculate Indefinite Integral: Calculate the indefinite integral.The indefinite integral of 2xdx is x2+C.
Evaluate Definite Integral: Evaluate the definite integral from 10 to 13. We substitute the upper limit and the lower limit into the indefinite integral and subtract the two results. So, we have (132)−(102)=169−100=69.
Write Final Answer: Write the final answer.The value of the integral from 10 to 13 of 2xdx is 69.
