How to find logarithm


For the common logarithm use the LOG key to the left of the 7 key. For the natural logarithm use the LN key to the left of the 4 key.
In either case press the key and then enter the value or expression whose log you want.
For example, to calculate the common log of 3, press
LOG 3 ENTER

LOG 5 ) / LOG 3 ENTER
or
LN 5 ) / LN 3 ENTER

I have data entered in L1 and L3. And I want to take the log of L3 in L2. But after I do that it gives me an error. How can I fix this.


Hi,
If the data in your L3 list contains only positive numbers there is no reason why you should not be able to calculate the log of the list and store that in L2.
  1. You open the list editor, [STAT][1:Edit]
  2. Use arrows to position the cursor on an element of L2.
  3. Use UpArrow to highlight the L2 heading (at the top of the list) and press ENTER.
  4. The data entry line will show L2= ..
  5. Erase anything that may be on the L2 entry line and type in
  6. [LOG] [2nd] [3] (L3) to enter the L3 identifier inside the log (
  7. Close the right parenthesis. Screen shows L2= log(L3)
  8. Press [ENTER]
  9. The L2 list will be populated with the logs of the elements of L3.
Hope it helps

How to calculate the antilog please


The antilog is the inverse of the logarithm. Not too surprisingly, it's invoked as the 2ND shift of the appropriate log key.

For the common antilog, use the 10^x key (2ND LOG). For example, 2ND LOG 3 ENTER gives 1000 as the common antilog of 3.

For the natural antilog, use the e^x key (2ND LN). For example, 2ND LN 3 ENTER gives 20.08553692 as the natural antilog of 3.
