A parameterization of the semicircle, x2 +y 25, from (5.0) to (-5,0) in the clockwise direction is Select one: 0 a. r(t) = ãcos(t),-sin(t) for t E [-5,5. b, r(t) â cos(t), 5 sirki)) for t E [0, Ï]. c. r)(cos(), sin()) for t e [0, x. d. r(t) = (5 cos(1), sin(t) for E [0, Ï] e. r(t) = (5 cos(t),-5 sin(t) for t E [0, Ï].
