In Exercises 57-60, identify the reasoning process, induction or deduction, in each example. Explain your answer . It can be shown that 1 + 2 + 3 + ⋅ ⋅ ⋅ + n = n ( n + 1 ) 2 I can use this formula to conclude that the sum of the first one hundred counting numbers, 1 + 2 + 3 + ⋅ ⋅ ⋅ + 100 , is 100 ( 100 + 1 ) 2 = 100 ( 101 ) 2 = 50 ( 101 ) , or 5050.

Select the correct answer below:
The function f(x) is continuous.
○ The right limit exists. Therefore, the function is continuous.
The left limit exists. Therefore, the function is continuous.
The function f(x) is discontinuous.
○ We cannot tell if the function is continuous or discontinuous.
1.3. The dots of Output 2 lie in pairs. Why? What property of esin(x) gives rise to
this behavior?
1.6. By manipulating Taylor series, determine the constant C for an error expansion
of (1.3) of the form wj−u' (xj) ~ Ch¼u (5) (x;), where u (5) denotes the fifth derivative.
Based on this value of C and on the formula for u(5) (x) with u(x) = esin(x), determine
the leading term in the expansion for w; - u'(x;) for u(x) = esin(x). (You will have
to find maxε[-T,T] |u(5) (x)| numerically.) Modify Program 1 so that it plots the
dashed line corresponding to this leading term rather than just N-4. This adjusted
dashed line should fit the data almost perfectly. Plot the difference between the two
on a log-log scale and verify that it shrinks at the rate O(h6).
