Consider the parametric curve given by
x(t) = 16 sin3(t), y(t) = 13 cos(t) − 5 cos(2t) − 2 cos(3t) −
cos(4t),
where t denotes an angle between 0 and 2π.
(a) Sketch a graph of this parametric curve.
(b) Write an integral representing the arc length of this
curve.
(c) Using Riemann sums and n = 8, estimate the arc length of
this curve.
(d) Write an expression for the exact area of the region enclosed
by this curve.
`Hey,
Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries
Parametric curve is
2)
dy/dt=10*sin(2*t) + 6*sin(3*t) + 4*sin(4*t) - 13*sin(t)
dx/dt=48*cos(3*t)
dy/dx=(10*sin(2*t) + 6*sin(3*t) + 4*sin(4*t) - 13*sin(t))/(48*cos(3*t))
dx=48*cos(3*t)dt
So, arc length is
So, arc length is 4.2421
Note: Brother according to HOMEWORKLIB RULES we are only allowed to answer first 2 part if there are many. So, I request you to post other part as separate posts.
Kindly revert for any queries
Thanks.
