a) Find the length of y=3x on the interval [1,3] by integration. Verify your answer using geometry. b) Set up an integral that would give the length of y=13×3{“version”:”1.1″,”math”:”y=13×3″}on the interval [0,2]. This integral is difficult to evaluate analytically. Instead of trying to evaluate it directly, write down a Riemann sum with four subintervals that could be used to estimate the integral. You do not need to do the arithmetic to evaluate the sum.

Your friend is attempting to find the total area between y=sin x and y=cos x on the interval [0,2π]{“version”:”1.1″,”math”:”[0,2π]”}. He comes up with this integral: ∫02πcosx-sinx dx{“version”:”1.1″,”math”:”∫02πcosx-sinx dx”} If he is correct, explain how he came up with this integral and evaluate it. If he is incorrect, explain what is wrong and offer a corrected expression.
