1. Access the help on integrals (Desmos) Ex and review the section about definite integrals and integrals with infinite limits, and examples from Integrals in Action. 2. In Desmos, using the graphs you created in Discussion 7, compute three definite integrals with the lower limit a and the upper limit b, and interpret the integrals in the context of your application problem, if: o a = 0 and b > 0 o a > 0 and b > 0 and b > a o a = 0 and b = tooThe derivative of the function is below, shown in blue: + VI X V = 2 + 1 x- +1 Ax X (x2 + 1) 2 d = 1 X -10 f(x) = 2 arctan(x) tx + C =1 X -10 10 and the antiderivative is shown below in purple: + # Oo = oo , y does as well. The graph of the antiderivative (purple) intercepts the y-axis at y = 1 this indicates the integration constant
