Repeatedly differentiating functions We’ll be able to generate these power series using something called a Taylor expansion. This requires us to keep differentiating a function (to get each extra term of the polynomial). Let’s practice this first. ? ?

Composite Functions We can also apply these when the input to the function is different. ?

Solutions to differential equations Just as some functions can’t be integrated (in terms of elementary mathematical functions), similarly many differential equations can’t be integrated. But we can use a Taylor series to approximate the solution. Bro Exam Note: This is by far the most common type of question in exams on this chapter.
