x = 5 cos t
y = sqrt(15) sin t
2) 3x^2 + 12x + 5y^2 -10y -58 =0
Since a=5 and b=sqrt(15) like above mentioned, but this ellipse is transformed so that the new center became (-2, 1), then is it that the parametric equations became:
x= -2 + (5 cos t)
y= 1 + (sqrt(15) sin t)
Many thanks to someone who helps!
