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.

sine

step-by-step explanation:

there is no grid

step-by-step explanation:

60.9774

step-by-step explanation:
