Consider the polar curve r(6) = 2 + cos ()9), 9 e [7675,767r]. b / 5(9) d9 If computes the length of the curve, then a = b = 5(9) = 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(z) for V2 (parenthesis are required) Write sqrt((cos(theta)+sin(theta))A2) for \\I(COS(9) + sin(9))2 Write sqrt((cos(theta))"2+(sin(theta) )"2) for x/(cos(0))2 + (Sin(9))2 Write pi for 717 Write x"y for xy
