One can use the tan addition formula to prove that? = 16 tan^-1(1/5) – 4 tan^-1(1/239). over three hundred years ago, the taylor series for tan-1(x) at x = 0 and this fact were combined to calculate the first 100 digits of a. estimate how many terms of the two series we should use to calculate those 100 digits. [2 marks] hint. the series for tan-1(239) converges much, much faster than that for tan-1(5). this means that to guarantee 100 digits of n using this approach, we should find an n such that the difference between 16 tan-1(1) and the nth partial sum for 16 tan-+() is less than about 10–102. you may use the fact that for a series satisfying the conditions of the alternating series test, the nth partial sum differs from the total sum by less than the absolute value of the (n + 1)th term. you may also use mathematica to pin down a suitable value of n.

the correct answer is 1: 2

it can be to see completed examples before writing, in order to examine what makes for an effective piece. see how these intros give some context before posing the topic and lead naturally into the body paragraphs, where the evidence will be listed. you can imagine how the author has organized the rest of the piece.

"we buried my cousin last summer. he was 32 when he hanged himself from a closet coat rack in the throes of alcoholism, the fourth of my blood relatives to die prematurely from this deadly disease. if america issued drinking licenses, those four men—including my father, who died at 54 of liver failure—might be alive today. that is a good example piece   some steps that are .
