Eliminate the parameter x=4+2 cos∅ y=1+2 sin∅ I think i can solve it like this but i am not sure x=4+2cos∅ x-2=4cos∅ x-2/4=cos∅ 2/24/2014 | Daisy from Memphis, TN | 1 Answer | 0 Votes Mark favorite Subscribe Comment
X = 4 + 2 Cos θ Y = 1 + 2 Sin θ (X- 4 ) /2 = Cos θ ( Y -1 )/ 2 = Sin θ ( X-4 ) ^ 2 + ( Y - 1 ) ^2 = Cos ^2 θ + Sin ^2 θ 4 4 ( X - 4 ) ^2 + ( Y -1 ) ^2 = 4 Equation of a circle centered @ ( 4 , 1 ) with radius 2 2/24/2014 | Parviz F. Comment
