(a) Based on knowing the zeros of the sine function, what number would you guess Euler was talking about when he uses the symbol p above? (b) In .11. of the same document, Euler introduced the symbol 1: in the phrase \"where 3: denotes the total perimeter of a circle whose diameter is = 1.\" What does this phrase imply the value of p is? Does it agree with your conclusion from part (a)? (c) Why are these the zeros ofthe function 1 15223 + %;45 + - - - , as he claimed? (d) 1Why is the number 0 not on Euler's list of arts? Isn't the sine of D equal to 0? Euler concluded .16. with a very familiar task, polynomial factorization, presented in a somewhat unfamiliar way. Hence the divisors of this equation will be 13,1+3,1i,1+i,etc. P p 2P 2p
