Coordinate Geometry in the (x,y) plane
Question 1 of 1
1. How confident are you that you can write:
a. parametric equations in Cartesian form?
The Cartesian equation of the circle x2 + y2 = 52 can be written in terms of a third variable (called a parameter) as x = r cos θ, y = r sin θ.
The parametric equation of a curve is given by x = 3 – t2, y = -2t. Write the equation in Cartesian form.
The Cartesian equation is y2 + 4x – 12 = 0.
