HP Prime for All

English  Русский 

With HP Prime, you can choose whether to operate numerically in the Home view or symbolically using the CAS in the CAS view. For example, press H and enter 8 in the Home view to see 2.828… or press K and enter the same expression in the CAS view to see 28

These workshop materials use the default Textbook setting.

Example: Infinite Series

Screen Right Suppose we wish to explore the series 1+23+45+87+169...

To begin with, we can compute the first few partial sums.

  1. Press H to enter the Home view.
  2. Type 1 and press E
  3. Press +3/2E
  4. Press e to cycle through its decimal, proper fraction, and improper fraction forms
  5. Continue as shown to the right until you have the first 5 partial sums

Another approach is to use lists. In the figure to the right, the List L1 is first defined to contain the 1 st partial sum (1), followed by the numerator and denominator of the following term. The second line adds the next term to the sum, then adds 2 to the numerator and multiplies the denominator by 2, and stores the result back into list L1.
From there, just pressing E generates the partial sums.

To use the CAS, we observe that the sum can be rewritten symbolically as:


  1. Press K to open the CAS view.
  2. Press c to open the template menu and select the summation template
  3. To enter n=0, press ASn>0
  4. To enter + at the top, tap on the top and press + , then S9 and tap on
  5. Tap on the right template box and enter the rational expression.
  6. When you are done, press E

Home and CAS views are just the tip of the iceberg. Move to HP Apps to explore rest.
