Series | The Direct Comparison Test with 2 Examples

The video tutorial explains the direct comparison test, a method used to determine the convergence or divergence of series by comparing them to known series like the P series and harmonic series. Through examples, it demonstrates how to apply the test to both divergent and convergent series, emphasizing the importance of choosing a suitable comparison series. The tutorial concludes with key points on when the test is conclusive and when other methods, like the limit comparison test, may be needed.
