Hi Jessa,

So I think I got 1 through 3 for you (below), but for #4, could you confirm if this is what the function looks like before I start:



\(\arctan \left(\sqrt{y}\right)-3x+2y=0\)

* arctan means inverse tan-1

Okay, so in that case the first and last term become 0, and the middle term becomes -3, leading to:

-3 = 0, which doesn't make sense Sad Dummy

Really not sure about that one, have you been given the answers by any chance?
