(b) Use the Comparison Theorem with f x 1 s x to show that x2 t x d x is divergent. (c) Illustrate part (b) by graphing f and t on the same screen for 2 x 20. Use your graph to explain intuitively why x2 t x d x is divergent. re r 3 dr e 2 x2 x x /2 e ; 48. (a) If t x cos 2 d z2 2 s y sin x x , use your calculator or computer to make a table of approximate values of x1t t x d x for t 2, 5, 10, 100, 1000, and 10,000. Does it appear that x1 t x d x is convergent? (b) Use the Comparison Theorem with f x 1 x 2 to show that x1 t x d x is convergent.
