Use the following formulas to set up two integrals for the arc length from (0, 0) to (1, 1). Observe that one of these is an improper integral. (I) L = b 1 + dy dx 2 dx a (II) L = d 1 + dx dy 2 dy c L = 1 dx 0 = L = 1 dy 0 = (c) Find the length of the arc of this curve from (−1, 1) to (8, 4).

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
