- In this project, you will use spreadsheet software (either Microsoft Excel or Google Sheets, please) or Desmos explore the Sine Integral function (sin(t)/t, t0 t = 0° Si(x)=s sinc(t)dt, where sinc(t): 1, to By using the Midpoint, Trapezoid, and Simpson's Rules with n = 20, you will approximate the value of Si(5). You will also use a Taylor Series representation of Si(x) to approximate Si(5). Answer the questions below (either print this page or write or type on your own document). You will need to submit your answers as well as your spreadsheet and/or Desmos graph link. Make sure that your spreadsheet/Desmos graph is very well-organized so that I can look at it to see how you performed each calculation. If you need help using the technology, see me in office hours, ask your classmates, see a tutor, or seek tutorials on the internet. 1. Use the Midpoint Rule to approximate Si(5) with n = 20. Write the approximation here with at least 8 digits after the decimal. 2.
