Make all obvious simplifications.

Let C denote the curve defined by the parametric equations
x = sint
t cost
y = cost + t sint
You are to find the arc length of that portion of the curve that lics
between the two points with parameter values t=0 and t = r.
[One way is to calculate dx, then dy, then dx , then dy', and then
%3D
ds = ydx +dy. Finally, calculate the arc length as a definite integral
of ds. Or define a vector-valued function and use ds =r'(t) dt.]
