hey whats up,

ok i have a question on differentiating parametric equations. The question says to find the equation of the two tangent lines to the curve. here's the equations...

[tex] x = 6 cos t [/tex]

[tex] y= 2sin2t[/tex]

Now, after i differentiate them, do i just plug in the corresponding point? , here's what i got after i differentiated them...

[tex] \frac {dy}{dx} = \frac {2cos2t} {(3)(-sint)} [/tex]

after plugging in the corresponding point for t, i will have the slope, but is that slope for both of the equations?
