1) Eliminate t to give an equation that relates x and y.
x=(e^(2t))+9 and y=e^(7t)
2) Eliminate t to give an equation that relates x and y.
x=tan(t) and y=sec^2(t)-3
3) Show that this equation represents a circle by rearranging it into the centre-radius form of the equation of a circle. State the coordinates of the center and the radius of the circle:
LOLWUT?! Help would be soo much appreciated.
