Find the equations of the tangent lines at the point where the curve crosses itself. (Write your answers as a comma-separated list of equations.) x = 2 − πcost
y = 2t − π sint
−π ≤ t < π

Find the arc length of the curve on the given interval.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,

mrb

multiply each one by 3.14

step-by-step explanation:

10+4√2 is the answer. i dont have the time to explain.
