How to Use the Convergent or Divergent Series Calculator

Follow these step-by-step instructions to analyze your series:

Step 1: Enter the Series Term

Type the general term of your series in the input field. For example, enter 1/n^2 for a p-series or 1/n for a harmonic series. Make sure your expression is mathematically correct.

Step 2: Select the Test Method

Choose the most suitable test from the dropdown menu:

  • Nth Term Test – Determines divergence if the limit of a_n is not zero.
  • P-Series Test – Used for series of the form 1/n^p, where p is a constant.
  • Ratio Test – Checks convergence by evaluating the ratio of successive terms.

Step 3: Click “Calculate”

Press the Calculate button. The tool will show a progress bar, simulating the analysis process, and then display your results.

Step 4: View Your Results

The results section will display:

  • Series Expression: The exact series you entered.
  • Test Method: The method used for analysis.
  • Result: Indicates whether the series is Convergent, Divergent, or Cannot Determine.

Step 5: Copy or Share Results

Use the Copy button to save results to your clipboard or the Share button to post your series analysis online.


Practical Example

Suppose you want to determine if the series: ∑n=1∞1n2\sum_{n=1}^{\infty} \frac{1}{n^2}n=1∑∞​n21​

converges or diverges.

  1. Enter 1/n^2 in the series input field.
  2. Select P-Series Test from the dropdown.
  3. Click Calculate.

The calculator evaluates the series and displays:

  • Series Expression: 1/n^2
  • Test Method: P-Series Test
  • Result: Convergent

This quick check confirms that the series converges because p = 2 > 1.
