The following polynomial is defined on the interval [-2, 2]:

f(x)= x + 7x² - 4x -10.

The function is then extended to the entire x-axis so that the extended function is periodic.
a. Find the Fourier series for this function.
b. To what values does the Fourier series converge to at the end points, x= - 2 and x = 2?
c. Keep only 2, 5, 10 terms in the Fourier series and plot them in the same plot (no need to turn in your code); also include a plot of the original function. Compare them.

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
