Answer:
Step-by-step explanation:
We have the conversion from polar coordinates to cartesian as
x =rcost and y = rsint where (r,t) are the polar coordinates
Also all trignometric functions are periodic with period = 2pi
Using this we find out

Thus we converted polar to rectangular coordinates.
Reverse would be
from (x,y) to (r,t) as

False because parentheses go first.... just follow PEMDAS
