Visualize pi/2 as 90° on the unit circle. this has no real component, only imaginary. same for 3pi/2, or -pi/2 as shown in this equation:

as you move around the unit circle, you'll find that 9pi/2 is the same angle as pi/2.
Thus, the rectangular coordinates are:

Hope this help and plz give me brainlist.
1. 9/3
This is because 3 = 3/1, and if multiplied by 3/3 becomes 9/3.
2. 4/2
See above, this time we multiply by 2/2
3. 20/4
See above, this time we multiply by 4/4
4. 5/5
See above, this time we multiply by 5/5, and since our whole number is 1, due to the identity postulate, it will equal 5/5
