Hi,

I'm completely lost in this problem .... can someone help me pls?

Consider the parametric equations x= 4*cos^2(θ) and y = 2*sin(θ)

and fill this chart.

When t = -pi/2, x = ? and y = ?

When t = -pi/4, x = ? and y = ?

When t = pi/4, x = ? and y = ?

When t = pi/2, x = ? and y = ?

I also have to graph the equation in my pgrahing calculator. I tried to do it but I don't know if I did it right.
