Rewrite the parametric equations in cartesian form x=3cos t, y=-sin t

Hello from MrBillDoesMath!

(x^2)/9 + y^2 = 1

Discussion:

x = 3cost =>     x/3 = cost

                         y    = sint

Using  (sint)^2 + (cos)^2  =1 and substituting the above x and y values gives:

(x/3)^2 + y^2  = (cost)^2 + (sint)^2 = 1  or

(x^2)/9 + y^2 = 1

Thank you,

MrB
