Consider the polar curve r09) = 2 + cos Ga), 9 e [781z,78:r]. E; / 8(0) d6 If computes the length of the curve, then a = b = |:l |:| 3(0) = Answer entry help: No blank spaces are allowed in the answer fields Write theta for 9 Write x*y for x ' y (* is required) Write cos(theta) for cos 9 (parenthesis are required) Write sqrt(2) for V2 (parenthesis are required) Write sqrt((cos(theta)+sin(theta))"2) for (cos() + sin(l9))2 Write sqrt((cos(theta))"2+(sin(theta) )"2) for W Write pi for 71: Write x"y for xy
