Question

5. Eliminate the parameter and write the corresponding rectangular equations: x=3-2sin theta and y=1+5cos theta

Answer 1

(x-3)/2=-sin theta
(y-1)/5=cos theta
(x-3)^2/4 = sin^2 theta
(y-1)^2/25 = cos^2 theta

adding them bouth: (x-3)^2/4 + (y-1)^2/25=1

Answer 2

Thank you so much!! :D

Answer 3

Another quick question: Graph the equation r= 1 – cosФ. Use observation to state the symmetry

Answer 4

it's something like that
