Create a value of 31 x in the interval [0; 3] with a uniform division of 0.1 and calculate the function cos (x) at these points. Calculate the trapezoidal formula based on the points with the integrated and the same built-in function integrator. Which statement is true based on the results? Choose only one: a. The trapezoidal formula gives a value of 0.0056. b. The two values are equal to three decimal places. c. The trapezoidal formula gives a value less than 0.1230. d. The trapezoidal formula gives a value 0.1410 higher. e. With the function integrator we get a value 0.1411 higher.

A cable hangs between two poles of equal height and 30 feet apart. Set up a coordinate system where the poles are placed at x=−15 and x=15, where x is measured in feet. The height (in feet) of the cable at position x is h(x) = 17cosh(x/17) where cosh(x) = (e^x+e^-x)/2 is the hyperbolic cosine, which is an important function in physics and engineering. The cable is ______ feet long?
