How does on eliminate the parameter from a given set of parametric equations and obtain a rectangular equation that has the same graph? Specifically for this set:
x=t^(3)+t+4, y=-2(t^(3)+t)

what do you think? any idea?

anonymous · Answer

I saw you write something, where is it? Hint: what is the similarity between x and y ?

$\bf x=t^{3}+t+4\qquad \qquad  y=-2(\color{red}{t^{3}+t})\ \quad \
x-4=\color{red}{t^3+t}$

Oh...so x is simply going to be equal to y? Well, something that is the same in x and y I guess? If it's that simple, I feel kinda stupid XD

yeap

hahaha... @jdoe0001  "yeap" for what? for "I feel kinda stupid"?
