CALCULUS II, TEST IV 7 Problem 5 Answer all the following questions. (a) Find the Maclaurin series representation of the function f ( x ) = sin( x 2 ). (Hint: The Maclaurin series of sin( x ) might prove useful here, if need be!) (b) Use the series in (a) to evaluate the integral Z sin( x 2 ) dx as a power series. (c) Use the series in (b) to write out the Maclaurin series representation of Z 1 0 sin( x 2 ) dx (Do not compute and add the terms of your series!) (d) Find the minimum number of terms you need in the series in (c) to approximate Z 1 0 sin( x 2 ) dx with an error less than 10 - 3 = 0 . 001? (Show your work!)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
