Chapter 11.1, Problem 34E

Find the horizontal and vertical tangent lines of the cardioid r = 11-11 sin(0). (Express numbers in exact form. Use symbolic notation and fractions where needed. Give your answer in the form of comma separated list.) y =

6a) Let A be the parabolic arc defined by the equation y = 8x – x over the domain interval [0, 8]. Sketch A on a set of coordinate axes below; identify the coordinates of both intercepts and the vertex. Estimate the length of A using the lengths of the two line segments joining either intercept to the vertex. Write the definite integral that represents the exact length of A. Do not evaluate this integral - just set it up and simplify it. Then, use technology to obtain an estimate of this integral's value. (report it correct to the thousandths place) b)
