3. Evaluate LLA" (4- y2) dydx by using polar coordinates.

3. Find the polar equations x-3y+2=0

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

What is the rectangular form of the polar equation? 27 0 = 3 V3 O y 3 Y = -/3x Y = V3x -V3 O y = * 3
