Consider the function f(x) = 1 − cos(x) x 2 . (a) evaluate limx→0 f(x) = l. (b) as x → 0, at what rate does f(x) → l? (c) compute f(x) as written on a computer for values of x = 10−1 , 10−2 , . . , 10−10. comment on your results. (d) suppose that we are able to represent floating point numbers with n decimal digits of accuracy. around what value of r will the evaluation of f(x) produce very large relative errors when |x| < r? (e) rearrange the expression for f(x) to a mathematically equivalent expression so that the this new function evaluates accurately for very small values of x. verify the success of your rearrangement computationally. a

grab rope, tie a loop-de-loop, put it around ur neck, now jump while its tied to a high place. now your shoes are cool.

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
