3. Justify your answer to part 2 by converting polar equation to rectangular equation. =2/sin 0 t / 4 T /3 A-0 t /2 2π 3 3π/4 5π/6 3n / 2

6) Perform the indicated operations. Leave the result in polar form. [50(cos 236° + j sin 236°)][2(cos 84° + j sin 84°)] [125(cos 47° + j sin 47°)]

What is the polar form of the equation? 2 (x + 2) + y² = 4 O r(r+ 4 sin 0) = 0 O p2 = 4r cos O O r(r+4 cos 0) = 0 O p² = 4r sin 0

1. Match each equation in rectangular coordinates with its equation in polar coordinates: (a) x² + y² = 4 O r²(1-2 sin² 0) = 4 r(cos 0 + sin() = 4 r = 2 sin 0 Or=2 (b) x² + (y − 1)² = 1 O r²(1-2 sin²0) = 4 r(cos+ sin 0) = 4 r=2 sin 0 r = 2 (c) x+y=4 Or² (1-2 sin² 0) = 4 r(cos+ sin 0) = 4 r = 2 sin 0 Or=2
