Part B
(a) Because , which never equals zero, the object is never at
rest.
so the object’s speed is
Position is the antiderivative of velocity
Since P(0) = (0,0), arcsin + c = 0, and thus c = 0.
Since and thus c = 2.
Then
Solving x = arcsin for t yields t = 2 sin x. Therefore
Since 0 ≤ t ≤ 1 means 0 ≤ x ≤ , then cos x > 0, so y = 2 − 2cos x.
(a) To write the Maclaurin series for f (x) = ln(e + x), use Taylor’s
Theorem at x = 0.
