For the regions R below, write f dA as an iterated integral in polar coordinates. (Use t for theta in your expressions. ) With a = , b = , c = , and d = , f dA = f dA, where dA = d d
Answer
usepolar coordinates the given region is the portion between the circles of radius 3 and radius 4 with center as origin in the 1st and 4th quadrant so, the region Ris the polar rectangleis, in polar coordinate the area frdrdt where dA-rr
