Define a relation S from ℤ to ℤ, where x y means x squared equals y where x ∈ ℤ and y ∈ ℤ. a) Write S as a series of ordered pairs in set-roster notation (remember, you can use …ellipses…)b) Write S in set-builder notation. c) Does the relation S meet the criteria to be a function

The value of sin(x) (in radians) can be approximated by the alternating infinite series create a function (prob3_2) that takes inputs of a scalar angle measure (in radians) and the number of approximation terms, n, and estimates sin(x). do not use the sin function in your solution. you may use the factorial function. though this can be done without a loop (more efficiently), your program must use (at least) one. you may find the mod() function useful in solving the problem.
