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.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

step-by-step explanation:

d 600 because 15*10*2=300

300+300=600
