MATH 2301-100 Spring 2022 Calculus I Recitation 9 Week 13

Work in a group of at most 4. Explain to those who do not understand. Ask questions if you do not understand.

  1. A particle moves in a straight line with velocity (in feet per second) given in the graph: velocity function
    1. (15 points) Determine the position function \(s(t)\) at \(t=1\), 2, 3, 4, 5, 6, and 7, assuming \(s(0)=0\).
    2. (10 points) Sketch a graph of \(s(t)\). Make sure your graph shows where \(s\) is concave up and where it is concave down.
  2. Consider the integral \(\displaystyle \int_{-1}^2(5x-2)\,dx\).
    1. (15 points) Find a formula to approximate the definite integral using \(n\) subintervals and the Right Hand Rule.
    2. (10 points) Find the limit of your formula as \(n\rightarrow\infty\) to find the exact value of the definite integral.
  3. Use the Fundamental Theorem of Calculus to evaluate the integrals:
    1. (10 points) \(\displaystyle \int_{-1}^2(5x-2)\,dx\)
    2. (10 points) \(\displaystyle \int_{-2}^{3}(x^2-3)\, dx =\)
    3. (10 points) \(\displaystyle \int_{\pi/6}^{\pi/4} \csc^2(x)\,dx =\)
    4. (10 points) \(\displaystyle \int_{1}^{2}\left(\frac{x}{2}-\frac{2}{x}\right) dx =\)
  4. (10 points) Find \(\displaystyle\frac{d}{dx}\left(\int_{e^x}^{\ln(x)}\sin(t)\,dt\right)\)
