x = -x(x² + y² - 2ax - B) - y y = y(x² + y² - 2ax - 3) + x What is the correct polar coordinate form of this system? Sr (r = -r(r² - 2ar cos(0) - B) = α O Sr (r = -r(r² - 2ar sin(0) - B) 0 = = 1 (r = -r(r² - 2ar cos(0) - B) - fr = -r(r² - 2ar sin(0) – B) = α

4. Match each equation in rectangular coordinates with its equation in polar coordinates. (a) x² + y² = 4 (b) x²+(y-1)=1 (c) x² - y² = 4 (d) x+y=4 (i) r²(1-2 sin²0) = 4 == (ii) r(cos + sin 0) = 4 (iii) r = 2 sin (iv) r=2

3) (a) Eliminate the parameter of the parametric equation x = 4 sin and y =1+ 2 cos (b) Write parametric equations describing the motion of a particle moving under uniform linear motion from point A(-3, 2) to point B(9, -6) in 4 sec.
