- Consider the following integral: In(1 + x¹)dx In(1 A. When we first learned how to integrate / In(x) da we used the IBP technique. As far as you are able, please use the IBP technique to integrate In(1 + x4)dx. In B. Why did the IBP fail here? C. Without using a table of Maclaurin Series, represent f(x) = ln(1+x4) as a power series and find the IOC. D. Without using a table of integrals, please use the series you found 4 above to calculate / In(1 + x²)dx.arrow_forwardLet f(x) = k(5x − x²) if 0 ≤ x ≤ 5 and f(x) = 0 if x 5. - (a) For what value of k is f a probability density function? k = (b) For that value of k, find P(X > 1). P(X > 1) = (c) Find the mean. μ =arrow_forwardIn 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. Use the Trapezoid Rule…arrow_forward

- Sketch the graph of a function that satisfies all of the given conditions. f '(5) = 0, f '(x) < 0 when x < 5,arrow_forwardDraw the region bounded by the curves. y = 3x2, x = 0, and y = 3 Use the disk method to find the volume (in units3) when the region is rotated around the y-axis. units3arrow_forwardO Prove that the function f(x, y) = (x² + y²)e-(x²+y²) has infinitely many critical points and classify them. Guidance: After finding all the critical points, identify an expression in f(x, y) which repeats itself, denote it by t and investigate the function as one variable function. Afterwards, induce your findings from the one variable function to the original function.arrow_forward
