TI-84 CONICS app showing parametric trig formulas instead of standard form

[kstrickland06]

TI-84 HELP!
The formulas under the CONICS app keeps converting into trig... It saying a circle is
x=rcos(T) + H instead of (x-h)^2 + (y-k)^2 = r^2
How do I get the 'normal' formulas back?
PLEASE HELP!

Try hitting MODE, and make sure that FUNC is highlighted?
