Sec 11.3: THE INTEGRAL TEST AND ESTIMATES OF SUMS a continuous, positive, decreasing function on [1, inf) Convergent THEOREM: (Integral Test) Convergent DivergentDinvergent Test the series for convergence or divergence. Example: Test the series for convergence or divergence. Example:

Sec 11.3: THE INTEGRAL TEST AND ESTIMATES OF SUMS a continuous, positive, decreasing function on [1, inf) Convergent THEOREM: (Integral Test) Convergent DivergentDinvergent When we use the Integral Test, it is not necessary to start the series or the integral at n = 1. For instance, in testing the series REMARK:

For instance, in testing the series REMARK: Also, it is not necessary that f(x) be always decreasing. What is important is that f(x) be ultimately decreasing, that is, decreasing for larger than some number N. REMARK:

Example: Special Series: 1)Geometric Series 2)Harmonic Series 3)Telescoping Series 4)p-series

Sec 11.3: THE INTEGRAL TEST AND ESTIMATES OF SUMS a continuous, positive, decreasing function on [1, inf) Convergent THEOREM: (Integral Test) Convergent DivergentDinvergent Integral Test just test if convergent or divergent. But if it is convergent what is the sum?? REMARK: We should not infer from the Integral Test that the sum of the series is equal to the value of the integral. In fact, REMARK:
